"That and his abrasive, bordering on rude, delivery. And it's a shame because he has a good message. He pointed out many of the problems with software patents and the difficulties with being able to develop software independently. If you have any sort of success, you might easily run afoul of someone that claims a patent on your idea. He games examples of the gzip/pkzip fiasco and a few others. He showed how hard it is to find a patent, decipher the filings, and even the problems with patents that are under consideration. All pose problems and Mr. Stallman is right, we need to do something."
