> We already have bunch of laws and directives to make companies behave more ethical, since they made it clear that they need laws sometimes to do the right thing. How is this adding another attack vectors to kill their competitors?

I'd go as far as saying that such regulation fixes an attack vector. Before, a company behaving pro-socially was at a competitive disadvantage - their competitors that "never wanted to behave in a pro-social manner" could adopt antisocial strategies that the pro-social company couldn't. Banning those strategies levels the playing field.
