I still disagree with that Jov - people who work for a large company need their company to be successful just as much as people who work for small companies.
Also, consider this: ALL companies are in it "just to make another buck". Large companies like Activision exist because of investors. Those investors might be big-time millionaires, but they also include small-time middlemen. They might be included in mutual fund bundles as well. If a bunch of people pirate Black Ops, then Activision doesn't make as much money, investors don't get as much money, the average joe's retirement account isn't worth as much, etc.
I know this is all on an irrelevant scale when you're talking about a single person pirating instead of buying, but when you talk about the HUNDREDS OF MILLIONS of people who pirate games and software, it can take a HUGE chunk out of overall profit for software and game devs. Now I know that not every pirated piece = what would have been a sale, but you can't argue that none of those pirates wouldn't have bought the software if they hadn't pirated.
Also, the more "blockbuster hits" that Activision or any other large dev puts out, the more interested people will be in investing in game development, both in large companies, and in small indie companies.
Ultimately, if piracy wasn't an option, we'd see more people purchase games, we'd see more money invested in games, we'd see more developers interested in taking chances on new and unique ideas for games, and we'd see more games available, period.
If you think a game is too expensive, don't buy it, or wait until the price drops. If you think a game is terrible, don't buy it.
If you think Photoshop is too expensive, don't buy it. Look for a substitute that will work for what you need. I found Paint.Net for free, as well as Jasc PaintShop Pro that does everything I need it to do. There's no reason for the average joe to need Photoshop. If you're a graphical artist and really need the features from photoshop, pick up an older copy of Photoshop on the cheap until your artistry skills create enough money to buy the latest & greatest.
