Ugh, sorry. His feed is annoying, too. Here's the comment:
@raucao why would this make decentralized illegal? Why can't I go to any (for example) mastodon instance and say "what do you know about me?" I expect almost all of them to say "absolutely nothing"
@john Because it is utterly impossible to tell you which server stored what about you and to delete it remotely.
@raucao I think you're looking at Mastodon or the fediverse as the network. If each instance is considered its own network (which happens to federate with other networks) - it's up to the user to interrogate servers. Just like with GDPR the consumer has to figure out who to ask, there's no centralized clearing house.
