bsky started with nine of its posts. wing shown publicly so when they flopped the switch (i think they also opened registration without invites) some people who had gotten used to their post being hidden from the rest of the net felt exposed and the devs added this settings.

while i do not think its a great setting i kinda get it. especially given that there are not (yet) private accounts so that’s the best they have

i doubt that because if they did it what reason would there be to not use one of the many chromium derivatives out there?
