If you had been watching this campaign from the start he worked with Microsoft and a few other corporations trying to get stories into the news. Once he had contacts with the journalists his "articles/posts" became much more inflammatory and he began getting more and more citations. It appears from my perspective that the early articles were to get credibility with the press so that a more elaborate attack campaign could be bred using the contacts and history of citation. As time has moved he's moved from factual based discussions to wild accusations and speculation without a basis in fact at all.
IMO it's similar to corporations using established advocacy groups to petition for causes completely unrelated to their advocacy (for money). For example, several major national advocacy groups like the GLAAD (Gay Lesbian alliance) were paid advocates in support of ATT's purchase of T-Mobile. (in the case of GLAAD the membership revolted and fired the director for doing this).
Mueller is a plant who's being paid to create a campaign of FUD. He's been questioned numerous times about who is behind the campaign and if you read his responses carefully you will note that he never responds to the question. I'll at least give him credit for not lying about it, he just refuses to answer the question. But make no mistake, there is an organized campaign of FUD going on here and Mueller is at the front of it.
Personally I expect that his backers will walk away once the Google purchase of Motorola Mobility goes forward, with 17,500 patents and another 7,500 in process that are almost entirely mobile phone based Google will be the new heavyweight patent holder in the mobile sphere. Mueller will have to look for someone else to pay for his FUD.
