If you have two choices, namely no money and some money and you must have money to eat then you don't have two choices. There is no choice, because the other platforms are far too small to compete. What should arguably happen more is uploading to more than one location, but searching for youtube alternatives is almost impossible (at least if you want one that actually has some potential. There is a ton of trash).
It just needs a start
TLDR: A few people may do it, but it won't scale.
People can complain as much as they want (and sometimes rightly so) but it's a simple technical truth that nobody else can provide a Youtube-quality service for free. The operating costs are just insane.
Most people posting on YouTube have day jobs or other means of support. I'm actually tempted to think that patronage and ad supported models lure a lot of people into thinking they can monetize their hobby in a significant way that they would never think they could if they were playing a musical instrument for tips.
Essentially, if you don't like your job, stop complaining and quit!
People invested significantly in YouTube because they were promised that it was a platform for everyone.
Now they are gentrifying the platform and driving everyone off who isn't a major celebrity, via gaslighting.
If you are a celebrity like Logan Paul, the rules simply do not apply to you. YouTube will fully monetize anything you put up, up to and including violating the terms of service or even committing actual crimes in real life.
YouTube is perfectly capable of treating people better, they just choose not to.
People can see it is wrong when Uber does stuff like this to contractors who are far less invested in the platform, but YouTube gets a free pass to abuse its contributors.
