> it's no one's fault and no one's to blame

There's obviously somebody to blame. Somebody getting a legitimate domain taken down for hours should have consequences, if only to make mistakes more expensive for trigger-happy automated "IP protection" services (the only signal they'll probably understand).

The question is just if itch.io has the funding and energy to actually pursue the matter legally, now that it's technically resolved. I couldn't blame them for just changing registrars instead.
