First, why do you think modding is illegal? It's perfectly legal, at least in the way it's done on this forum.

You're complaining over nothing. The Education edition doesn't really have any "real" exclusive features; it's just streamlined for a classroom setting. In addition, I haven't seen any loss in sales of other platforms being caused by the Education Edition.
