Because I'm not willing to pay for Microsoft Word or Adobe Photoshop (because I don't use them) doesn't mean I don't pay for software. Lots of the software I use I don't have to pay for, but that's not the reason I use it. I use it because it's better than anything else out there. So I contribute money to projects instead. And I pay for services (like Newsblur rss reader) that run on open source stacks. And I buy plenty of games (but only if they run on Linux).
