Someone at the Free Software Foundation seems to think that an effective means of promoting free software is to actively campaign against Microsoft’s new Vista operating system, and created the Bad Vista website. I personally think this is somewhat like negative campaigns in policital races – attack the opposition rather than promote your own strengths.
This sort of action does more harm than good to the image of free software advocacy. I’m all for promoting the free, open-source software I use, and will do so here on the site as appropriate. But undertaking a negative campaign (some of it based on misinformation) and encouraging ridiculous stunts like Amazon tagging just makes the free software community look like a bunch of mouth foaming zealots.
Stick to the positives, compete on features, usability, and support. Thats how to win users over.
