iCloud is fine for syncing things between Macs (assuming you've turned on Advanced Data Protection) but at some point if you're treating it as a backup you WILL lose data.  Whether it's an iCloud glitch or you accidentally deleting or overwriting a file you needed, when you screw up on one computer it's now gone on all of them if you don't have an actual backup solution.

I did once manage to save a user who thought iCloud was a backup.  They'd trashed a file on their iMac, and hadn't opened their MacBook yet.  I pulled the bottom case and removed the WiFi board, then booted the MacBook and backed it up, put the WiFi board back in, and restored the file.  It was an expensive mistake, and if they'd opened the MacBook the file would have been gone permanently.

The Apple car didn't go anywhere.

It never existed in the first place.  Apple was NEVER going to build a car.

Wait, people still use Xitter?

Deleted the app from all my devices and deleted my Xitter account the day the elongated muskrat infestation happened.

And about time, too.  Apple is playing around, they're going to lose this.  They need to just open up the iPhone and iPad for apps installed from anywhere, it's time for this app store nonsense to end.

(Gave up and created a new account today, my old one won't log in and the password recovery won't work.  With how much the posts here have dropped I don't think I'm the only one who had that problem.)
