Not a Microsofter, but note that Bing has like "most non-Google search traffic". It's the default on Windows computers, and a lot of other search engines like Yahoo and DuckDuckGo use their data as well. It runs ads, so it's probably profitable.

And it's probably really good, this story as an example, to be in second place, when the first place runner is doing illegal things, under investigation in a dozen countries or more, and likely to face major repercussions going forwards. Being number two means you're number one when the leader gets knocked out of the race.
