People were screaming about where platforms and digital sharecropping was headed all along... and we're here now. Youtube, which is basically digital free-to-air is even more centralised than old free to air.
Youtube really is an extreme situation. They really dominate a whole medium single handedly and youtubers have shockingly little power in the whole thing. There either needs to be some neutrality, competition or youtubers need to organize somehow... unionize even. Trying to have a relationship with audiences that doesn't run through youtube won't work for most channels... even ones with millions of views.
I always expected a porn company to come in and compete with youtube at some point. They have the infrastructure. I've also been surprised at how restricted youtube manage to be, and still succeed... just the skin censorship if nothing else.
