From a profit viewpoint, why should Microsoft support Edge?

Hey **bleep** **bleep**, are you really getting on the chromium, cause I thought you had been on my ayrr for a few years now, oh Sorry did I say ayrr. I meant Firefox, like remember how I'd make foxes on fire, when I'd make them sleep quick, ay ay how deemann, ahh yeah great team you guys where, yes I said where and I meant it. But ay hot cakes, how's kessik feeling from the other nights khaabeet session, are the floor boards still wet. Or did little deb clean it all outta you. If only you had a clue how big and bad Firefox will be very soon, like no one will even see or know what happen to chromium,, oh I also noticed there was an Eddie you where having secret codes with aswell, could that be the one and only Eddie aoun, the one you and your bros call kherrouyee cause yoqus say his always sh...t. in his pants. Oh please hotcakes, qi need your advice on this one. Do I chose the ballistic tips or the hollow points. Please get back to me, and if it's too late or you aren't able to reach my aayyrr just come to the garage, by the way did you well Paul about the 2 pitbull pups you sold just to get on the bags and get an ovaries check from me, did you also tell him how you would get Really naughty when youq would hit the pipe aswell, hey it's all good, il be making things easier, how bout we just come out and show them how hard you have been working when you have me over, I understand your blind but is zubbree that big that it's blocking you from seeing me record myself bending you over or is it because you like to remind me that your ex Ellie and his little zubboora brother that got you press, yeah how you tell me that they are watching and to show them how there Louie should be getting the good ol chromium. La neek the chromium le teelih min teezik, feel free to reply here or on my device that qyou have been texting non stop recently. How's the dsp going how's Ray Ray, how blowass story coming round this time for yous, little bit different dont you say. Hmmmm anyway look how's this, either give me my 2 cubs back asap so I don't put yous all away, or maybe we can have an open one as you've made claims and I get to khabbiit you and deb at the same time and never stay there, as long as you go tomorrow and do clear or cls or what ever on the system. And there's always the last option and we will leave that for a different blog.
Never trust a woman who doesn't trust or respect herself, and never take back something that was never yours to begin with, Harry's a hell of drug.

While I agree with everything you're saying, you haven't really answered my question. All of the reasons you've given here are altruistic (that is, morally good.) Two major companies working on optimizations, a better user interface, more features, and less work for extension developers are all "nice" things to have, but they aren't easy to monetize. I guess both Microsoft and Google need fast browsers for their business software suites to run on, so maybe I was being too cynical about it in this post.
