Serious question for those that this is relevant to: if you don't understand how ActivityPub works, even a little bit, why do you feel the need to have opinions on how it should work?
Isn't this backwards as hell? Shouldn't you try to understand how something works, then ask why it is that way and if it's intentional?
Too many people here have this strange opinion that they have some sort of privacy, even if their profile/posts are set to "public".
This is just simply not true. We're on the internet. There's over 20,000 Fedi instances and there's just no way to manually parse them to make sure there's no "bad actors" using your "public" posts for whatever the hell they want.
We already see this happening with things like NewsMast which is aiming to be a "news" app where their users don't have to login or register to a Fediverse server, yet they will see posts by Fediverse users from bigger instances based on "categories".
Maybe do some research about how the protocol works and how it's VERY opt-out to the core, before you have opinions on it. Just saying....
#FediBlock snarfed.org and brid.gy for bridging fediverse folks to Bluesky against their will (and in likely contravention of GDPR in the EU) with typical Silicon Valley techbro sense of entitlement:
“[O]pt in results in far fewer users, and users are critical for a bridge to be useful.”¹
