Paying someone for promoting your product or message. I don’t think it’s all that complicated. Talking about your own product on the internet is fine. Paying to promote your message wouldn’t be. TikTok and Reddit and Instagram aren’t trying to keep people endlessly scrolling because they are free-speech fanatics. It entirely comes down to “more time in app = more revenue”. Take away that monetization method and you take away the single incentive that has driven virtually every dark pattern that has developed in social media in the last two decades.

Subscription based services have exactly the same incentive to increase engagement.
