Now that the cat is out of the bag, iCloud data has to be secured from access, just like any iOS device. The FBI and DOJ have made sure Apple is going to make it impossible to access the backup they could have had if they didn't botch the password because they are stupid and unfamiliar with how iOS devices backup to iCloud, and how resetting the password will stop the backup. Plain ignorant stuff, only average consumers would be found doing, changing the password when they forget it, and then nothing syncs and nothing gets backed up.
I just can't believe the ignorance level at the so called FBI forensic lab. They should all be fired. They are so stupid and/or ignorant our national security cannot be entrusted to that crowd.
