It’s not just Sony: Google and NVIDIA have also raised concerns with the FTC about Microsoft’s Activision deal

Google and NVIDIA also raised concerns with the FTC (US Federal Trade Commission) about Microsoft’s acquisition of Activision Blizzard, fueling the government’s case against the $68.7 billion deal, reports Bloomberg, citing people familiar with the matter.

The companies have joined Sony in raising issues with the deal, which the FTC sued in December to block it. The commission argued that the deal would hinder competition in the video game industry and scheduled an internal trial for August. Either company could be subpoenaed to testify as part of an FTC proceeding.

Google and NVIDIA have provided information that supports the FTC’s key claim — that Microsoft may gain an unfair advantage in the cloud, subscription and mobile gaming market — according to the people, who asked not to be named because the process is confidential. In its comments to the FTC, NVIDIA emphasized the need for equal and open access to the studio’s games, but did not directly oppose the acquisition, according to one of the people.

Microsoft for the first time announced a deal with Activision almost a year ago, looking to add blockbusters like Call of Duty and World of Warcraft to a business that already includes the Xbox console, the Halo and Minecraft franchises. But regulators worry that Microsoft could make it harder for rival platforms to have unfettered access to Activision’s most popular games.
