He touched a very important point. Many people do not realize that GPL and LPGL are fundamentally incompatible with patents (intentionally) and that in many cases it is a ticking bomb.<p>When he writes "The software license permits you to redistribute and use the code, but the MPEG-LA can still stop you", he means section 7 of the GPL (2.0). I think many people who use the GPL for their software do not realize that later on a single company (patent holder) can stop the redistribution of that software.
