Even if this had locked you permanently out of iCloud, you'd still have local access to data on device. And even if Apple somehow could remote lock you out of your devices there would still be offline backups.Aaaaand people seem to wonder why I avoid Apple ID, iCloud, biometrics, etc. as much as possible... could something like this possibly be one reason why?
To me this is a reminder that backing up and having a plan for restoring your data is important.
What I find most disturbing is the lack of communication from Apple. Hopefully there will be something once the incident is resolved.
