"Best" for whom? Any action has the potential to be either good or bad, depending on who you ask. But if it has a positive impact on society as a whole - that's probably good enough. And striving to do the right thing, upholding important beliefs like fair access to justice and freedom of speech, these certainly fall in that category. If a smaller company, or even one of us on HN had sued Apple would that suddenly make it okay? Apple's actions haven't changed, why should the identity of the plaintiff matter? Regarding your specific example - if Amazon is doing something wrong, then an antitrust case should be brought against them too. But that doesn't (and shouldn't) give anyone the right to continue doing something unethical and illegal.
