Erno Rubik didn't do anything. The seven towns company did.Yeah all these law suits from Rubiks company is a bone in the throat for the cubing community.
Erno Rubik should do more to help speedcubers, and not just make profit.
@qwr I did mention Ron van Bruchem somewhere at the back of this thread and Bob Burton is on the poll. Tyson Mao is another noteworthy mention.
