Fuck Satya Nadella. I knew something was being cooked up when he brought this up in that MSNBC interview.
These Congress members, like Maria Cantwell, probably have MS money connections through funding (Maria Cantwell herself getting almost $600K in funding directly from Microsoft), and are trying to legitimize an otherwise batshit insane theory that, somehow, Sony had to pay off Japanese developers to not release Japanese versions of their games for the dead XBO, the XBO that Microsoft killed over there due to treating the market like an afterthought. But somehow that is Sony's fault.
These brainlets don't even realize they are insinuating that the Japanese government are involved in collusion by pressing these claims, and I'm sure it's a great idea to piss off one of your few Asian political allies in the Pacific while China and Russia seem to be rolling ahead on great terms. But it's not the first time American politicians have messed things up with global partners, and it won't be the last.
The hilarious part is that when you actually look at 8th gen Japanese releases, virtually all of the big Japanese games came to XBO globally. FF XIV didn't, but that's because Microsoft rejected crossplay in the 360 gen. SFV didn't, but that's because Sony co-funded the game and sponsored it for CapCup. FF VII Remake didn't, but that's because the game ran into dev issues and Sony probably stepped in and wanted exclusivity in return.
Now, if there's only one way they can maybe prove Sony are in the wrong here, it's in relation to cross-gen games post-2020. Now I guess it can be considered "interesting" that we've been seeing PS4 versions for tons of games that don't have any XBO versions available, such as RE4 recently, but that could also be explained through MS officially discontinuing the XBO in 2020, phasing out both it and the One X, and revamping their XDK into the GDK which would have made devs less inclined to spread their cross-gen resources across two wildly different SDKs and APIs (considering for one of the, XDK, it'd be for officially discontinued consoles seeing a lot of upgrades to the new Xboxes anyway).
That's honestly the only leg of a hope & prayer these Congress people have in trying to prove Sony guilty in doing this, otherwise they are just looking for a scapegoat to dump Microsoft's failures with the Japanese market and Japanese developers onto, and oh hey it just happens to be the company that was most against the acquisition. What a surprise.
