Closed source with MS tracking and spying from the network logs. There seems to be an army of MS fanbois that angrily downvote any comments critical of crappy MS products in the thread.
Nobody would ever confuse me for a Microsoft fan-boy, but I personally feel more comfortable with sharing telemetry data (which both Google and Microsoft collect) with a software and services company than an advertising company.
More than 80% of Google's revenue comes from advertising (source cited below).
The majority of Microsoft's revenue comes from cloud services, Office, and Windows.
But I understand Microsoft has a trust gap with many folks, based on their anti-OSS activity of the late 90's and early 00's, and I'm glad we are all free to choose.
The only major browser (by market share) that is truly open-source is still Mozilla Firefox.

What is that if not spyware? Do I consent to them taking that data? When is it ever non legitimate by that ridiculous metric? I don't want any company to have my data for "legitimate business purposes". What benefit is it to me? How is taking data I didn't want them to not spyware? Is it paranoid to not want to be tracked by your brower? If you want to be tracked by your brower, why do you care about privacy or think privacy is?
All of them want your browsing data for their advertising for totally legit reasons you say. So why bother with privacy if you want them to take your data?
My main browser is Firefox with Sidebery. That's what Chrome should copy. Edge's vertical tabs are the next best thing...especially when you need a chromium based browser.
