Losing all access to my collection of Kindle books hurts the most. Note to self: STOP giving money for Kindle books. You don't own them. You rent them and when you lose your account, you lose access to the books.
@johanbove I haven't but I suspect it might be like leaving Google, sort-of Hotel California-esque. E.g. I've left Google services, but still have an account as I use an Android, and because someone else might otherwise claim my name as their account. W leaving Amazon do you mean AWS hosting etc, or also their e-book silo?
