Yeah, the fifty million they dropped on the movie is practically zero; they earn it back the instant it goes out to theaters, and once they reach the magical line of $0, they ought not make a profit. The whole point of movies is to entertain people, after all; it isn't a business!
I mean, I get that you aren't physically stealing a disk and then kicking a baby, but it's hardly justified. In the end, someone put their time into something, often doing something that few people can (As terrible as Transformers was, they truly did have some revolutionary graphics with millions of polygons and animations in the faces alone). While I find DRM and anti-consumer behavior appalling, it's a far cry from justifying not paying.
If you have a problem with their policy, stop consuming their product. Are we really all such blind consumers that we can't live without their DRM laced crap? Do we need it to the point where we'll blatantly break the law just so we can have their shit for free? We can't honestly take our money elsewhere?
By God, I can connect this to cars!
Say that you design a bloody brilliant car. Everyone wants to own it, but it's a little pricey. Well, you set it out in the world, all of these copies of your prototype. Someone buys your car, and figures out how to copy it. He copies it a few hundred times, and just starts giving them away to people. Suddenly, the car you designed is being produced rapidly by someone else, without any flaws in the new model at all. People caught with the copy of your car argue that they were never going to buy your model, that it had some sort of flaw in it that prevented it from going over 70 Mph which made it suck.
In short: If you can't afford it, if you're too lazy to go get it, if you think there's a flaw in the software, or if you can't get it in your region...don't get it.
