The biggest blockchain competitor to YouTube by a mile is LBRY / Odysee. That could integrate into the ATProtocol and host on BlueSky / Twitter. And then Twitter can bootstrap all of the other competitors that join on chain. And people could freely move from one protocol to the other seamlessly through a single account they control web3 style.
LOL bro what are u thinking, obviously he will put DOGE at the forefront of any crypto-related anything he'll do with Twitter.
I wouldn't worry about it as he'll be using Dogecoin obviously.
