I was referring to Microsoft offering Mojang help or whatever they want / need to release their games on a Microsoft-owned platform in the future.
They could still accept Mojang games, but offer the company absolutely no support when it comes to releasing their games.
He already trash-talked before the meeting, and that's what I was referring to. They should not have bothered inviting him at a dinner at all.
EDIT: Like GOG asking Bethesda for an Oblivion release here, and Beth trash-talking GOG about them using Inno Setup for the installers (or something else, just an example). Beth should be dead immediately in GOG's book, and if they want to release a game here sometime in the future, they should contact GOG first, not the other way around.
