Perhaps YouTube gets all their content for free, but it certainly isn't free to transcode video, host it reliably, and distribute it while moderating it (given how bad Twitter is right now I'm sure they have a decent number of measures in place, even if they aren't even "good" at it). And if it was remotely easy, believe me, there would be a lot of competition in this space.

Yes, I make Alphabet x dollars richer (or really, I make YouTube operate at a slightly lesser cost) every month by paying a subscription. And actually, I'm okay with it. A tiny cut of it goes to content creators and I get a nice piece of tech. And I support the branch of Alphabet that has technology that I think is incredibly useful and beneficial. If there's a content creator that I like especially then I'll support them directly.

The reality of it is that things cannot be free. Or at least it seems that way, because we have not been able to provide a free video hosting service that doesn't take advantage of its content creators or consumers.
