Going by comments in the post, the required login is coming in waves, so not all people may notice immediately.
Still, as Reddit is strong-arming its way across, maybe worth signaling to people there that the fediverse may be used without an account, so long as there’s even one instance that implements logged-out view as the protocol allows it?
I don’t have access to my account any longer, possibly VPN ban, though I never tried to recover it so I can only guess why mine is lost, else I’d post myself.
They’re only doing it to stop scrapers from having free access to posts. That’s their main product right now and they want to make sure they get paid for it.
