Err, that's not really the point of free software. The free software movement is more about freedom than not paying money (libre vs gratis).
You really want to stick it to the man? Pirate proprietary pay-for software. But you wouldn't want to do anything illegal now, would you?
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.
Use Gimp or buy Photoshop?
But this is reality, and the reality is that pirating is easy to do even with all the DRM/anti-piracy stuff that is in place.
For those that would use open source, it's a net a loss.
It's like the old saying: "Only thing worse then being talked about.."
Only thing worse then being pirated is not being pirated.
