It’s even worse than that! There is no delete all feature ! So if you have 100k photos and make the mistake of saying yes to Google Photos just once , it will fill up all your storage space, block your email until you pay for extra storage, then force you to delete all your photos manually, one page at a time, before you can stop using it. I think that trap is the sleaziest thing I’ve seen Google do.
This was even more annoying when they started including whatsapp backups in your quota and sent a load of people over quota.

It can then be decrypted with a simple access to the _sim card_, i.e. a way to receive a message, meaning that anything backed up to Google drive should not considered safe from a dedicated state actor (even if the other party did it). It is quite easy to demonstrate with a new phone or an emulator.
