Is it a better deal than YouTube? Last I heard TikTok has a pool of money they distribute in some magic way that's not directly tied to either company revenue or a video's view/like counts.
That essentially becomes their demonetization strategy, if you say things tiktok/ad sellers don't like, you stop being recommended. Youtube on the other hand at least separates their monetization from their recommendation system.
The model of feeds adopted by YouTube and Instagram has a lot of first mover advantages which makes succeeding as a newcomer really hard. It's really hard to find successful creators in the past few years that hit success without recurring to paid promotion or sponsorship from other more successful creators.
