@mcc great thread. I've been thinking about this, and about the ActivityPub alternative. Which to me looks like either
- Best case: "Gertrude" can speak freely on a friendly instance (which she used originally) and unfriendly instances/users can block her. But she keeps posting to her audience
- Worst case: "Gertrude" is banned by her instance, and now does not even have the option to continue speaking to her followers, she has to start a new account/identity from scratch, try and integrate into the community again, prove she's not an impostor, etc
With ATProto you don't get that best case scenario. But you don't get that worst case scenario either.
Btw, I saw pfrazee say they don't do PDS deletions except for illegal content (since they have to by law in that case). But on that note, they could even go further if they wanted (I think?) and block PDS migrations at which point we are back in the worst case scenario.
The comparisons and tradeoffs here are really complex! Just starting to wrap my head around it.
