> In what way does Microsoft benefit from people using Edge?

Every installation of Chrome on Windows is an opportunity for their most dangerous competitor to siphon off future opportunities. Anything which reduces that number is a fundamental win.

They also get to direct some percentage of users towards their properties (e.g. Bing) which do make revenue.

Finally there's the opportunity cost of not being in the game: having users in their camp gives them moves which they would otherwise not have. (Similarly Bing—some might call it a relative failure, but it's a roaring success compared to never trying in the first place. It was a good decision.)
