I think MS is making money elsewhere so they don't need browser market share but they do need to provide a browser.

On Windows (and corporate environment) one reason is that it is easier to manage. Comes with Windows, updates via Windows update and Microsoft provides support (for those with agreements).

It's much faster. Microsoft ripped out about 30 different Google-specific components, I think @ericlaw tweeted the list a little while ago.

Additionally Microsoft pay attention to developers. Chrome Devtools has has a Headers tab, with response headers and then request headers. There's a seperate tab called 'Response' which only contains the response body. I fed this back to Google (suggesting a request and response tab with headers and body) and (per Google) the response was from an engineer saying they personally liked it so therefore there was no reason to change it. Microsoft's feedback was they're actually looking at more logical layouts.

Well if it comes pre-installed with windows then that's one big reason. As a power user, I'd probably install another browser. But given that this is basically Chrome, there's not a lot of reason for an average user to switch.

If Microsoft integrates all the functionality of the original Edge into Chromium Edge, then it will be a great browser to use on their Surface line of tablet computers. Without those features, it’s a non-Google Chrome with a large company backing its feature updates and contributing to the codebase’s continued improvement, along with syncing features and potential better integration with Windows. Firefox has a lot of good features still, but its small usage amount has made some development budgets ignore it or drop support of it on some sites I have visited.

This is Chromium. Maybe you mean Chrome. Someone would use this over Chrome if someone doesn’t want to be surveilled by Google. Of course now you’ll be surveilled by MS. It is better when your surveillance dossier is split among multiple entities.

I assume they bet on people who want to use the Chromium engine without all the Google stuff and corporate people who use macs but work with MS infrastructure (like Exchange and Sharepoint).

Well speaking for me personally, Firefox runs terribly on my Macbook and it would be nice to have an alternative to Chrome.

Firefox runs rather poorly on Mac.

I think you can ask yourself that question with a lot of Microsoft products these days, and we use (and like) a lot of them at my place if business.

I mean Microsoft has the upper hand compared to Google or AWS because they are better at GDPR and privacy shield stuff. Microsoft is also miles better in terms of enterprise support, but it’s those reasons and not their solutions that sell.
