To be honest, i really do not understand what the hell is going on here. Firstly, and we all have issues with the fact that it is all digital copies, yet it has limited of them. That is pointless and causes problems for schools who use it. Like let's say the school is trying to make kids read something, and all the copies are gone. If they do not fix this(which they could in seconds), they are going bankrupt, so i hope this was helpful.
