They're directly lobbying the government on a massive scale. They're looking for every opportunity to force their software on people buying any computer, like they always have. They're looking for every technical trick to screw the competition, and to extract more from their customers. Where it's possible (i.e. not LibreOffice) they're buying up any company that does threaten to successfully compete with them. They bought half the video game industry for example. They're buying their way into all the schools so kids grow up knowing nothing but the Microsoft life.
I mean what else would they do? It's Microsoft.
