Youtube isn't free, and unlike a simple blog, requires tons of infrastructure and content creation. None of that is free, and people wanting that to be free is why we're in adscape hell.
Edit: I'd love for a competitor to youtube, but there isn't. Rumble isn't a real competitor, and none of my favorite channels place their content there either.
I wish there was a youtube alternative that was more of a federation, but every attempt I've seen of federations have been mess.
