I always found what Bluesky was "optimizing" for to be a stupid goal, and inherently a bad idea -- namely "the ability to keep your everything permanent."
That's EXACTLY what brings MORE danger to centralization. I get that losing an identity on a thing sucks BUT WE'VE ALREADY DEALT WITH THIS WITH EMAIL, and more over the ability to lose/destroy/start over -- like with email -- is a FEATURE as much as it is a bug.
