This is incidentally why I'm not developing an Activity Pub homeserver myself -- I have no interest in having users doxx my politics simply because I'm interested in social networking protocols.
Personally, my hobby is no longer computers, and it definitely isn't FOSS -- I'm not trying to be the next guy blackballed from the industry for having the wrong thought about the current thing. That's also why I have a throwaway account here. Political activists working inside the tech sphere are savage and have no mercy, and I wish to have nothing to do with them. For me that mostly means: no ActivityPub, no Twitter.
