I'm curious how much this one guy, all on his own, has stalled passkey adoption.

In theory, this issue could never touch average users. It's only power users who use standalone open-source password managers. All the options normal users are funnelled into aren't going to expose passkeys in plain text (except maybe Firefox?), and thus aren't going to be phishable in any meaningful sense.

But this guy opted to tell the open-source community that having exportable passkeys is wrong, full stop, and that open-source implementations might get banned for allowing this, planting a gigantic red flag right next to the very idea of passkeys, making every single power user who sees that post (which is linked on every thread which touches on passkeys) either completely reject the idea, or approach it with extreme caution. And thus no power user will recommend it to anybody else, not to mention the general usability problems they have.

I guess if it weren't him, the same ideas would have been made clear in other ways.
