Taking functionality away from a product after you bought it is a scum move. If the law lets them get away with it, the law should be changed.

When I buy a product, I look at reviews and make my purchasing decision on the features and functionality at the time of sale. If a software update later ruins that, I want the option to get my money back.

A scum move? Such drama. It's what every shrink wrapped software company does unless you're paying "enterprise software" licenses that have more protections... with commensurate prices.

Violating license agreements is also a scum move, but the 3D printer community online is mostly entitled juveniles, so they'll just get away with it I guess.
