Dave Winer responds at length to Sean Lyndersay of Microsoft's lengthy response about their RSS patents. Dave suggests that Microsoft's RSS patent are based on free community IP and calls the patents an obstacle to growth in the market. That's a fair criticism, unlike most all of the others that have been floating around. He's not saying these patents are invalid. On the other hand, it's not like Dave didn't profit from RSS. This leaves me with an old question, "Is Dave the only person allowed to profit from RSS?"
