Pursuing Piracy Hurts Proprietary Software
We've already pointed to the backlash against the BSA for its activities, and now we're seeing how these kinds of crackdowns are doing exactly the opposite of what BSA/SIIA members would want: they're looking for open source alternatives. Following the ongoing "international crackdown" on software piracy, it appears that the Vietnamese government is the latest to start promoting open source alternatives.
After all, as Microsoft and others have long admitted, you're much better off if someone is using an unauthorized version of your software, than if they're using the competition (especially if that competition is free).
However, by putting such a big effort into cracking down on software piracy, all the industry has done is highlight why people are better off going with free alternatives.
