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.
