I think it's important to remember that taking away the ability to re-download your initial purchase/license (whatever) whenever you want, doesn't really have anything to do with your license to use the copies already in your possession (I mean legal use, of course). Those are two separate things.

Even if your online account is shut down and/or you lose access to your previous "licensed" files... you're still perfectly within your rights to continue to use/read the copies that are already on your device/app (provided the initial purchase was "legal"). Nobody's demanding that users immediately delete legally licensed copies of ebooks from devices/apps when someone signs an exclusivity deal. And no one should be trusting any company to keep copies of all their purchases on their servers until the end of time anyway.
