I'm sorry but I fail to see the problem with this. DeepMind has made very impressive demos and papers, but they have yet to add one dollar of revenue to Google's bottom line. Further they have drained billions from Google.
Google has to, somehow, get completely out of the research paper game and into the product game.
Papers have to have little/no impact on perf going forward. Other than a small windfall to goodwill they are a misalignment between the company's goals and those of the employees.
Products Google, products. Unless Larry and Sergey want to turn Google into a non-profit research tank. Which would be fine, but likely with substantially lower headcount. Even they aren't that wealthy.
