kingfisher, you are confusing as hell.
Human beings, even those working in corporations, are responsible for the choices they make. It's that simple. I'm not allowed to shoot someone who cuts me off in traffic, nor should I be. More similarly, if someone bullies me, that does not give me the right to turn around and bully the next person lower on the totem pole. I shouldn't do stupid things that hurt the people my company actually values, either.
Your willingness to claim that people aren't responsible for their own actions is not just absurd, it's pathetic. We are not animals, and we don't get to excuse are bad behaviour by pointing the finger at others. We ultimately get to decide how we act. The pirates don't get to excuse their piracy by saying "but I bought a game once and it wasn't as good as it promised so I'm just going to pirate future games as revenge", and the companies don't get to say "we aren't getting anything from these people who don't pay us money, so we have the right to screw over the people who do".
And I shouldn't (and don't) support companies that exhibit this kind of behaviour. I, at least, am perfectly capable of doing that. I can't do anything to stop pirates - well, beyond conversation and persuasion, which I do do fairly often. But they aren't a threat to me, and don't actually harm anyone, so I reserve my ire for the groups and individuals who do, through their abuses of legislation and their corrupting influence. There's not a whole lot I can do their, either, of course. But I'm certainly not going to start being apologists for them.
