If I was Microsoft, I'd wanna know too. After all, it's a race for every single one of our data points, and then some.
Either way, you gotta admit it's ironically funny that Microsoft wants to keep/poach Chrome users into their own... wait for it... Chromium-based browser.
If I was Microsoft I would be investing in a some market that no one has clear dominance in. Right now they are trying to manage inconvenience. Making it harder and harder to not use their product. This strategy never works unless the government backs you up. They are trying to be like Comcast. You want to be like Apple. You want people to pay a premium for what they consider the best.
