Personally, I think the FTC convinced no one that their arguments have any merit to secure an injunction. Instead of producing facts it just seems like they are trying to corner MS into saying something that they can further use as ammo, but I think MS has done a decent job of not putting themselves in a trap they can't talk their way out of.
Funnily enough, if the FTC got their way initially, yesterday would've been the end of the trial and I still think they would've lost still in incredible fashion.

Still, who knows what the fuck will happen. Most people thought the CMA wouldn't have blocked and the EU to follow the CMA's lead. The whole fucking merger has been chalked full of surprises.
