I don't see where he is threatening anybody? He's just stating the obvious. If you promise to store a key in a non-exportable format and then create a big export button, websites won't trust your software.

Then you follow the procedure you would follow for when you'd forget your password. Probably a password reset through email, maybe calling customer support. Or if you have it set up, you could use the passkey set up on your phone or Yubikey or whatever to log in and create a new password on your new PC.

Passkeys aren't passwords, that's the whole point. It's modelled after the "something you have" factor, not "something you know". If you're finding workarounds to violate the security design, you're not gaining any advantage by using passkeys. Just use a password if you want to use a password.

The trouble is, if websites are allowed/encouraged to ban clients, then the advantages you're talking about come with the downside of hard-tying yourself to one of 3 US-based Big Tech companies, because those will be the only ones who will ship clients declared "secure." That's not a trade-off I'm willing to make for something as critical as my service logins. You can already see this happening, almost every article talking about passkeys assumes you're logging in with an Apple, Google, or Microsoft device.

This is a downgrade from passwords (and exportable passkeys), where I can just restore it from a backup.

Yeah, that's what I plan to keep doing, unfortunately. What I'm worried about is a password-less future where that's no longer an option and we all have to submit to using one of Android, iOS, or Windows to log in to everything because those are the only clients that can be trusted(TM) to handle the user's data as the big tech companies and governments desire it to be handled. This is a dark future.
