It was an announcement made by MS surrogates and it was promoted as true internally at MS, I personally head it through the grapevine from current MS employees. They really did try to get people to believe it as part of their billion devices push. I didn’t believe it because I know MS lies all the time, which is probably why they don’t make official statements about such things and generally work through surrogates.
Maybe next time they can create a poly market bet.
