> I guess this could be true that YT "shaft[s] creators in every way possible". If this were true, I'm somehow guessing that not basically everyone would show their videos there, don't you think?

The fact that content creators are still using Youtube doesn't mean Youtube is not shafting content creators. Youtube has killed most of their competitors so it's not like content creators have other options right now, but I suspect new competitors will show up if Google continue to enshitify youtube.
