I see no issues with anyone being an asshole once others have driven them to that point. Should people continue to accept abuse and suffering from those who indifferently inflict it?
Corporations are conscience-lacking psychopaths, faceless cowards and abusers, and should be treated as such. They are cowards because they hide behind false appearances - the go-to method of dealing with their own shortcomings. And they are smart about it.
This point is beatifully driven home in a futuristic science-fiction novel "Accelerando" (which is free btw) where corporations based on smart contracts and AI threaten sentient beings uploaded into the net by publishing altered derivatives of public works to reposess unsuspecting readers's minds using copyright law.
