This is why you keep your e-books stashed on media you control, and put copies onto your Kindle when you you want to read them.
Same with any data you store on an iOS device. You never let a device you don't control have the only copy of any data important to you.
The Kindling never leaves Amazon properties; it is not yours even though you paid almost the full price of a book.
If there is rule of law in the US and EU, these will eventually become free e-books, that is, separated from Amazon; they will regain the status and properties of the book.
