It's okay that Bluesky will be successful and replace Twitter.
Most people like the service that a corporation gives to them. Most people are willing to trade the cons that go with that for the pros they receive.
I came to the Fediverse because I - personally - can't take those cons anymore. And the pros here work for me, again personally.
I don't need all the people in the world to use the Fediverse for me to enjoy the community here. Heck, most people didn't use Twitter. They used (and still use) Tiktok, Facebook, Instagram, and Snapchat more.
Let people use Bluesky. I hope they enjoy it and it enriches their lives. It doesnt for me, so I won't be going. But we already have a critical mass here and its fine.
