What rules are you referring to? No one is breaking any rule or law or anything really. This thread is a bad assumption about things 99.9% of the users here know zilch about.
Not talking about legality here, just the rules of game called ethereum mining.
That is the point... there are no rules in mining Ethereum that are being broken... some just feel it is unfair because they can't do it. Consider if you had to buy your mining software up front?
