They own the content, and they can remove access to that, whether it's created by you or shared with you.

If you are a Mac user, you probably know, or even use, Things 3, a professional planning app that makes a professional's life on a Mac-powered device much easier.
However, maybe you're one of those people who don't like to be in a 'closed garden' setup and have to endure some Apple scanning going on inside your device and so switched to Linux. (In fact, if you didn't switch to Linux yet, now is as good a time as any!).
