I have paid for much software, and consider that to be the right thing to do. Same as for MP3s, I may download a lot of them, but I own a vast CD collection, that actually outnumbers my MP3s, and then some.
People who boast of never buying anything - piss me off mightily. Perhaps if we all followed your paths then games would become obselete, as although I don't doubt the sincerity of the open source movement, it is unlikely that they would be into coding (complete) games on a regular basis.
