People are going to BlueSky precisely because it doesn't have AI, and X Payments, and other stuff...
The way I understood it, by posting to X/Twitter, you're giving it the permission to use your images/videos/text to train AI. Bluesky doesn't have that.
It's true that BlueSky will be scraped too, but it's about the Principle: "We're not allowing AI to profit off our Art."
