> why is a centralized “burn” able to completely prevent me from interacting with people using Bluesky?

Presumably to stop credential reuse attacks on Bluesky itself?

Bluesky is one instance and they should enforce security on that instance. If you use a previously burnt ID, they have no way to tell it's you (indeed that's the whole point!)

I've done some work in the DID space. Not really a fan, and the space is full of half working implementations like this post documents.

But this particular criticism seems unfounded.
