Nothing new is being revealed here. In fact, I think this tweeter could be reading the room incorrectly.Kotick is being honest here. He obviously has much to gain personally from the merger taking place but he doesn't agree with this. The only shocking thing here is a glimmer is dissenting honesty, but he likely has to say this because he's probably said it in writing and if he says something contrary that can be provided in evidence, that is perjury.
During the CMA investigation, ABK stated the exact same thing, they cited, that Call of Duty or their games be could not be found on a subscription service today or in the future unless they were acquired. This is a stark difference from EU recognizing their point here:
Even without this transaction, Activision would not have made its games available for multi-game subscription services, as this would cannibalize sales of individual games. Therefore, the situation for third-party providers of multi-game subscription services would not change after the acquisition of Activision by Microsoft.
Vs the CMA
“The CMA recognizes that ABK's newest games are not currently available on any subscription service on the day of release but considers that this may change as subscription services continue to grow,” representatives of the CMA wrote. “After the Merger, Microsoft would gain control of this important input and could use it to harm the competitiveness of its rivals.”
While the commentary here in the FTC PI trial is to show that Game Pass will harm consumers (good luck in trying to paint that picture - we have more varied content from a large variety of international sources now than ever), it's contradictory with what the CMA has leveraged here when coming to their decision. This could be a contention point as MS and ABK will go back to fight the decision in the UK later this year.
