Some unresponsible open source developers are definitely making Microsoft very angry. So very angry that make Microsoft forget that it is not Linux nor open source community that violate the patents. It's like blaming the whole country because of just some unresponsible people from that country. It's not the country that is to blame, just the unresponsible people. The guilty ones.

The open source community should also not protecting their members who commited crime. Otherwise the community would be marked as a community of violators. A case which should not happened. This is similar to countries whose goverment has no or very little interest on stopping movie piracy. Some of them are already marked.
