it's somewhat similar, yeah. minus the part where bluesky itself is by far the majority host of people's data. that puts it more in the realm of "Office 365 Online + OneDrive storage" than "Word" - a lot of people will lose a lot of data, though something resembling it can be started up again. and people with backups (their own PDS) will just move to OpenOffice for a bit.

Blacksky finishing their full forking does finally give them a much stronger leg to stand on for "bluesky is decentralized", though.

PDSes are great and I really wish Mastodon would support something similar. Mastodon's lack of account portability / data ownership / lightweight hosting is a massive issue.
