Secondly, creator-centric platforms don't pay off. Platforms bring the audience, creators bring the content. Platforms make creators, not the other way around. No creator got from zero to hero without a platform that has attained critical mass. That mass isn't attained by catering to the creators, but to the audience. The audience doesn't care about creators until the platform introduces them.
If creator-centric platforms paid off, there wouldn't be these insane commissions (often upwards of fifty percent) that creators are willing to give up just to be on the platform. Competition would drive commissions down. Rather, it's more of a winner-takes-all game, and those winner platforms get away with it. Low-commission platforms don't bring the traffic, and vice versa.
