Hmm,

One of the things that is notable about Youtube is there was once competition (Vimeo and Daily Motion) but they effectively outdistanced it. A bit like Amazon and Ebay. There are related things semi-competing like Twitch.TV etc, also, of course.

I suspect that the situation with the earlier video providers is that they were "bleeding cash" for many years until the process finally reversed - if they were the winner (again like Amazon).

I think this long capital investment process is what means that no one wants to or expects to step into the ring with a large, successful player. It took that player a long time to learn to be successful, that player will fight you to keep their relative monopoly and you will have to risk a lot of money.

Youtube content creators are effectively Youtube's suppliers. Youtube is squeezing and its "normal" - squeezing suppliers is part of the monopolist's playbook. Its unfortunately convenient for Youtube that people have been willing to make good quality video for nearly nothing since the tools to do so became cheaply available.

Why there is "no competition" for Nvidia, Amazon, Youtube, etc. Not that I like the situation but it's not an "unnatural" situation.
