on bluesky (sorry) the devs have been super active and responsive and eager to explain their approach. they have talked about this specific choice at length - that after an extensive ecosystem review and lots of thought, it seemed like a different architecture had a better chance of working at scale. I hope they find the time to explain this more publicly but it’s definitely a decision they didn’t make lightly.

More generally, I have a ton of respect for the standardization process and for the amount of (mostly volunteer!) engineering over the years that had gone into fediverse, but it’s been so long and growth has been so slow that I don’t think it’s unreasonable for a new project to try something different.
