I would imagine some of the dissatisfaction with life that some of the school shooters feel is at least, in part, fueled by constantly being bombarded by advertisement that is trying to make a sale by convincing them that their life is terrible as it is without whatever they're selling.
This is why the US is a constitutional republic designed with a lower house that was elected by and represented the interests of the people of the several states and a senate that was appointed by the legislatures of the several states and represented their interests.
The drafters of the constitution did not want the citizens of the country to have up and down votes about specific policy. Add to that the limited spread of information due to lacking infrastructure (and, well, a man on a horse on a several day's ride being the fastest way to carry news), and the populace would be too ill informed to be able to make a decision based on current facts. This is also why the US does not elect presidents based on popular vote and uses electors are representatives for the local voters.
The ebook no longer exists. That's the point. Whether or not the item is available in print is irrelevant as the person who paid for it did not pay for a physical copy.
It's an issue if there were ebooks exclusive to Microsoft and not available anywhere else. You've lost access to something that you can't get access to (legally) again at any price.
Maybe if you just dump a large number of unsorted files in place and do nothing with them. With a decent file manager and an hour or so, you can add many books and symlink them to the metadata directory with no issue.
