This happend to my kindle to! After keeping in in flight mode for years I put it online again in order to buy a few new books from the kindle store, poof suddenly my entire library of side loaded books was gone, with progress and everything. I could see random metadata files related to the books on the drive, be books was gone. Super annoying as many of the books I didn't have locally anymore and to loose the "archivement" of finished books sucks big time. I can see this may be implemented by amazon to counter piracy, but alot of these books was perfectly legal. So the result of this is that I will never put my kindle online again and just stop buying from the Kindle store.

Keep mine in Aeroplane mode. Download books I buy on Amazon directly from amazon and drop them into calibre. Amazon doesn't get to touch my Kindle ever.

Thinking hard if I ever want to get another Kindle when Amazon can just screw around with what I put on my Kindle ...

I just email epubs (as .txt) to my kindle's email address and they show up on the device in a couple of minutes. Never had any books just vanish.

I find it easier than converting to Kindle format and then copying over USB.

Why email epubs as txt? You can just email the epubs. I do it every day.

Same, though I don't think it is going to help Amazon the way they hope it does. I moved books over to my kindle and had it nuke my humble bundle collections when I added a purchase from Amazon. I've not connect it again until I figure out how to backup and restore MY metadata.

Won’t help with restoring metadata, but if you add books by using the “email to kindle” feature it will keep them in your library through syncs

I had an issue exactly like this with my iPad.
