The Generous Feature Is a Price Increase in Disguise

Based on the research ofZhu, Chen and Raghunathan, "Helping Oneself by Helping a Rival: Social-Media Platforms' Policies on Enabling Features for Influencers," Information Systems Research, 2026

Zhu, Chen, and Raghunathan model something every platform operator already feels in their gut but rarely says out loud: a social platform and its influencers both sell the same underlying thing, attention monetized through advertising, which makes them collaborators on the surface and rivals underneath. The platform holds the controls, in the form of design features like clickable shopping links, that determine how much of that attention the influencer can convert into revenue. Disable the feature and the platform keeps a bigger share of the advertiser pie for itself. Enable it and the influencer's channel gets more valuable, pulling some of that pie toward the influencer instead. The paper's surprising result is that the platform can come out ahead either way, including the case where it hands over the feature for free, as long as advertisers do not value the platform's own inventory much less than they value the influencer's newly enhanced one. The platform simply raises its own price to compensate. Two case histories from the last three years, both involving the exact feature named in the paper's own example, clickable links, show this playing out in public, in real time, with real numbers.

TikTok blocks a link, and says why

In March 2023, TechCrunch reporter Sarah Perez found that TikTok had quietly started blocking links to app store pages inside personal creators' bios, a change the company confirmed once asked. The links, used heavily in cost per install marketing deals between brands and creators, stopped working outright, returning an "action cannot be completed" message. Third party link in bio tools like Linktree were caught in the same block.

The telling part was the exception. TikTok business accounts kept full access to app store links, with no fee required to unlock the functionality, and the company simultaneously rolled out a new "Download app" button for those same business accounts. The practical effect was to sever a monetization path that creators and brands had been running around the platform, in CPI campaigns that never touched TikTok's own ad products, and reroute it through accounts TikTok classifies and can court for advertising. This is the paper's antagonistic branch played out with a precise, documented carve out: disable the feature for the influencer tier that competes hardest for the same ad dollars, and keep it open for the tier the platform can more directly monetize.

Instagram opens the same door it had kept shut

A little over a month later, Instagram did the opposite. On April 18, 2023, the company announced it would let every account, personal, creator, and business alike, add up to five links to its bio, ending years of a one link limit that had been the entire reason third party services like Linktree and Beacons existed. Mark Zuckerberg called it "probably one of the most requested features we've had." Instagram did not charge for it, did not restrict it to paying accounts, and did not cap it at some trivial number designed to look generous while changing little.

TechCrunch's coverage made the competitive logic explicit: Instagram's own reporting noted that the change landed soon after creators had been loudly complaining about TikTok's stricter bio limits, and that Instagram calculated expanded linking could be read as a competitive advantage, pulling creators back toward its app rather than away from it. That is the model's other branch: enable the feature for free, because the advertisers who matter to Instagram are not meaningfully worse off than they would be if the creator's content lived somewhere else entirely. Keeping the creator, and the audience attention around them, inside Instagram's own inventory was worth more than the small amount of ad-adjacent traffic the links would route elsewhere.

The math behind the about-face

Read side by side, these look like two platforms with opposite values. The model says they are running the identical calculation with different inputs. A platform only wants to disable a monetization feature for influencers when doing so protects advertiser revenue it would otherwise lose to the influencer's competing channel. It wants to enable the same feature, even for nothing, once it can recapture that value some other way, most directly by charging its own advertisers more once the platform's remaining inventory becomes relatively more attractive, or once keeping the engaged creator and audience inside the app is itself worth more than the ad dollars that would have gone to blocking them.

TikTok's bio link rule shows the fee branch of the paper directly: the abstract's extension case states that when a platform can charge a fee for the feature, it should "always enable the feature at an appropriate fee," because the extra revenue can come with no change to advertising revenue, a gain in it, or at some cost to it, depending on how the platform tunes the fee. TikTok's version of the fee is not a line item, it is accountification: pay to become a business account, and the feature switches on. Instagram's version shows the zero fee branch: no gate at all, because the competitive value of retention exceeded the marginal ad revenue at risk.

The platform did not do the influencer a favor. It found a cheaper way to raise its own price.

The free feature that still has a price

Meta's 2026 Reels test is worth sitting with, because it is the paper's no fee equilibrium happening in the wild as this article goes to press. Reporting from April 2026 describes creators able to tag up to thirty products directly inside a single Reel, with Meta explicitly stating it is not currently taking a commission on the links. That sounds like pure generosity, the influencer gets a stronger shopping tool, free. But the eligibility bar, a public account, a follower minimum, and compliance with monetization rules, means the feature is not actually open to every influencer competing for ad dollars on the platform, only the ones whose audience and behavior already make them valuable enough that keeping their attention inside Instagram, rather than routed out to an external storefront, is worth more to Meta than any fee it could charge directly. The commission free framing obscures that the platform is still pricing the decision. It is just pricing it through who qualifies rather than through what they pay.

The same tension runs through Instagram's own history with creator commerce, documented by Marketing Brew's retrospective on the link in bio industry: Instagram tested a native affiliate marketing program in 2021 that let creators earn a commission on tagged product sales, then shut it down about a year later. Third party affiliate platforms like LTK and ShopMy kept growing in the gap Instagram left open, precisely because the platform's walled garden logic, keep users and their clicks inside the app, kept bumping against creators' desire to be paid directly and transparently for driving sales. Every one of these moves, test, open, close, retest, is the same underlying game being replayed as the relative value of the influencer's service, the platform's own ad inventory, and the fee a platform could extract shift year to year.

The tell: who the platform is actually pricing

None of this requires bad faith on anyone's part. A platform enabling a once-blocked feature for its influencers is behaving exactly as the model predicts a profit-seeking platform should: it checks whether advertisers still value its own service enough to absorb a price increase, and if they do, it lets the influencer win, because the influencer's win is now funding the platform's own higher price rather than draining it. The losers in that arrangement are rarely visible in the announcement. They are the advertisers whose rates just went up to pay for a feature they were never consulted about and do not appear in the press release at all.

The practical tell, for anyone trying to read a platform's feature announcement correctly, is to ask not "who benefits" but "who else just got repriced." TikTok's bio link rule repriced the CPI campaign advertisers who had been running installs through creator links for free. Instagram's five-link rollout repriced nothing visibly, because the competitive stakes were about keeping advertisers' attention on the platform at all, not extracting more from the ones already there. Meta's free Reels product tags will, if the test expands, eventually show up somewhere: either in a higher ad rate for the advertisers whose inventory now competes with in-feed shopping, or in a fee the platform quietly adds once enough creators depend on the feature to make the fee hard to refuse. The feature was never free. It was priced into someone else's invoice from the start.
