So? Why is that a problem? My wife occasionally watches this old lady who's vlogged every day for over 14 years straight. She averages 150-200 views. The people who try to build a brand end up getting outsized attention so it seems like that must be what anyone would want, but most people actually aren't trying to do that.

Well, do you want a platform people watch videos on, or a platform people simply upload videos to, never to be seen?

It's not an either-or, but generally speaking, a platform centered around getting more people to watch is probably worse to have in the world than one centered around people just expressing themselves to a handful of e.g. family/friends/small communities. Especially if the former is really just a conduit for ads.
