It would be nice to see all the open source php projects out there once this site picks up. Nothing like good ol' free software to stick it to the man!
Beware that in some cases, that's still a net gain for the proprietary vendor: if you weren't able to pay much for, say, Photoshop, better to have you as a Photoshop user who will buy it at some later date, recommend it to your friends, and otherwise participate in the Photoshop using community, rather than, say, learn Gimp on Linux.
This is true, but there are many people who will always pirate no matter what. I know people who pirate everything from Photoshop and Windows to music and movies, not because they /can't/ pay, but because they simply don't want to.
I agree that it's not just about free software. Open source is a great movement for expression and challenges you to grow. But at the same time, aren't you sick of big companies making us pay for crappy software...uh um windows vista?
Last I checked, you're free to _not_ buy Vista. Buy a Mac. Buy a pre-installed Linux box. Buy your roommate's cousins used Pentium 4 w/o an OS and have your way with it.
