@jik Thanks for the reasonable reaction! I'm thinking about said controls as a band-aid for an already messed up situation (see the first part of my post). E.g. an opt-in system could make all historic posts followers-only by default. This wouldn't affect existing archives ofc. (which do exist whether we like it or not) and may be too much headache for users. We'd need arguments and compromises.
Calling each other names only conserves the current situation where one chunk of users is missing key features while an other is living in a false sense of privacy.
