In the midst of crisis, opportunity … a counter-argument to “Free Kills”

admin — Tue, 09 Feb 2010 23:42:55 +0000

Today I read this really insightful article about how giving away software can kill the market for it. While I largely agree with the Andy, I think that he has missed one important point. Giving away a really good product in a certain space can depress sales and stifle innovation, but there will always be that small percentage [...]
