Isn't that the whole point of bs? Empowering users to take their data where they want. It's completely open-sourced and well-documented. If someone buys bluesky you can move all your data to a different service that follows the same protocol
Can I move my followers/following graph as well? Moving the actual content is barely a consolation prize if you lose your entire audience in the process.
You can move your data, but whoever controls the AppView controls what people see “on Bluesky”.
