Is Piracy wrong? Yes. Is Piracy as much of a problem as a lot of people claim? No.
I'd quite like a Ferarri but I'm never going to buy one, going down to the local car store and jacking one is still stealing. It's not a lost sale, because I'm never going to buy one, it's not going to end the company, but it's still stealing the thing. Likewise my hopping onto a torrent site and downloading a game, fillm, music, etc is still stealing it (and no, stop, don't tell me that they're free to produce while a car costs materials. The companies behind the media paid artists - and a hell of a lot of other professions too - to create that data and my stealing it would still be a loss of return on that investment).
As for whether the game was made for charity or not, what does that even mean? What, it's evil to steal something made for charity but not by a corporation? Somehow theft is ok if you're simultaneously "sticking it to the man"? You ask who cares if Skyrim gets pirated, well you know what: I care. I honestly do. I found Skyrim to be an amazingly fun game that's totally worth the £40 I paid for it and I really do think it's unfair if some pirate downloads it for free. Not because (ok, not ONY because) of the simple jelously that they didn't pay for the same enjoyment I'm getting, but because I think it's unfair that a team can put so much work and so much love into a game and people don't pay them a fair price for it.
If you don't agree with a company's policies then either vote with your wallet and don't buy their stuff, or just admit that what your doing is wrong and steal it, don't try to justify your crime by turning yourself into a crusader for good against the evil corporations.
