The right to be forgotten can be argued as being even stronger in the fediverse.
Yes, you can't delete the content that you created, but you can delete the account associated with them, edit them, etc. with far more control than any corporate system gives you.
No there isn't a button to just "delete all things related to me" as some people want, but that wasn't what the right to be forgotten was about.
People knew the technical limitations of it from the start, the problem was that when users would take actions they thought deleted their content, private code would very much not delete it.
