Not sure on what grounds the student would sue but I'm sure that a creative and enterprising law student could come up with something ... “perhaps torturous interference with education”?
one could sue under equal access then again kids are expected to buy their own paper and school supplies so why should software be different?
“To be honest, this wont get the attention it need until a student who is being forced to purchase software files a lawsuit against the school.”
MS gets around that by dropping the price of their products for education big time. Business and Consumer users get screwed on MS pricing since they are subsidizing Education and Foreign markets.
