I’m guessing fedi software devs haven’t fixed my least favorite fedi software incompatibility, which is:
- Akkoma and Misskey handle replies to private posts incorrectly - if Bob replies to Alice’s followers, the reply is visible to all of Bob’s followers, even if they don’t follow Alice
- Friendica handles them correctly - it makes a list of everyone who follows both Alice and Bob, and only people on that list can see Bob’s reply to Alice
- Misskey interprets this as creating a group chat - thus when Eve replies to Bob’s reply, it mentions every single person who follows both Bob and Alice
