He's a patent lobbyist. Who exactly finances his operation is in part unclear (he seems to work for Microsoft on one project). He does not want to disclose his income sources. Some people feel that he's highly biased against Google etc.

FM is generally well informed, but may have a hidden agenda, you have to be awake when reading his opinions...

My main beef with his persona is that many news reporters call him an "expert" and publish his opinion as if were facts set in stone.
