That blogger is a known MS-biased lawyer. He worked with them for 20+ years and also worked with Blizzard for a period of time as well IIRC. He is effectively no different from Hoeg's Law, except AFAIK Hoeg has no active stakes or work history with Microsoft or ABK. But he may know/be friends with people who do.
I find it rather alarming how MS have so many legal people basically acting as influencers for them and ABK to try swaying public discourse and control the narrative in online discussion over this deal. If there's one thing these proceedings have truly made me come to hate about them, it's tactics like these. They feel slimy, dirty, dishonest, manipulative, and deceitful. It's not much different from the business practices Microsoft did in the '80s and '90s, except now it's been transferred to the public theater to play out like some demented reality show.
Just very crass and distasteful antics more or less.
