It's not hate. It's actually love.
In order for markets to be efficient, everyone needs to play by the same rules. If someone is circumventing rules for personal gain, that is not capitalism, that's cheating. Cheating discourages people from putting their money into a market, which makes it less efficient.
By letting cheaters or potential cheaters know that their actions are being watched, it hopefully disuades them from cheating. It's the exact same logic behind municipalities that plant fake cop cars on highways.
Now, it's when politicians start prescribing "cures" that I have a problem, but I don't mind them digging around and bringing facts to light--that is assuming they don't have an agenda.
