I often look at all the internet monopolies and I feel YouTube is quite a hard one to crack.
A competitor could buy some top channels, and then what?
YouTube is on virtually all decides out there, even bundled with smart tvs. So much to invest for a very low chance of return.
Why would top creators even agree unless you throw stupid money at them (they already are making crazy tens of thousands if not more for every video, good luck luring them).
And that's not even counting that Google has insane amounts of data for ads, yet another advantage.
I just don't see anybody being able to really fight YouTube unless Google itself keeps making it worse.
