It's a common misconception that tons of users manually install Chrome, but Google just pays PC makers to make Chrome the default browser.
Chrome is the only browser with a business model that makes sense to do this. Microsoft just doesn't make enough money from Bing/Edge to pay PC makers to leave Edge as the default. Firefox makes no money at all, and makes 95% of its revenue from Google's payments to be the default search engine. Safari isn't even available on Windows, and even then, 99% of Safari's revenue is from Google.
(Safari was available on Windows from 2007-2012, but it never captured much market share, because Apple was never willing to pay PC makers to make Safari the default.)
Here's StatCounter's estimates of desktop browser market share. The overwhelming majority of users are using their computer's default browser.

Chrome: 65.55%
Edge: 13.9%
Safari: 8.69%
Firefox: 6.36%
Opera: 2.9%
FWIW, I don't think it makes any sense at all to sell off Chrome. Google could probably sell off YouTube, AdSense, and Google Cloud, but not Chrome.
The only viable business model for a web browser, the one that literally all major browsers use, is to accept money from a search engine (Google, specifically) to be make them the default. Even Kagi makes its own Orion web browser, for exactly this reason.
How could Chrome make its owner any money at all if Chrome couldn't accept money from Google to be the default search engine? How could Chrome possibly do what Firefox and Safari can't?
