Yes, this is all true, but the monopoly part is YouTube was supported by Google search profits for most of its existence, which its competitors don't have. The good part is YouTube is a really good service (ignoring their handling of gun related videos), the bad part is there are no viable competitors. If you like (legal) content they want to limit, block or otherwise hobble, you don't have any other great option.

So YouTube is subsidized by Alphabets profits. Basically everyone in the world is better off apart from Alphabet shareholders and maybe a few giant corporations slightly smaller than Alphabet that want to compete if they were able to sell a worse product for more money.

If their competitors were any good, then google would have given them the money.
