Things improve.
It is not a natural law that things will eventually improve. It takes deliberate effort and money and an environment where this improvement is possible. Especially a video hosting site takes a lot of capital. And if powerful actors has a literal stranglehold on the market, then it can be virtually impossible even for obviously better alternatives to gain a foothold.
We should probably be thankful that that narcissistic manchild is so addicted to his social media. Imagine how much more destructive shit he could have accomplished if he actually put his mind to it.
