Chrome has just been a better product for the last 10 to 15 years.
Every other company has just failed to make a good browser because they lack the incentives to do so (have gone back and forth as a Firefox user).
The only competitive browsers are those already built on chrome or safari.
I'm not personally a big fan of Safari but it's bigger issue is that it is only available on one platform whereas the web is naturally cross platform.
Almost by definition Safari can't be the "winning" browser.
This feels like ruling that the iPhone is a monopoly in the US and that Apple needs to divest from phones.
Edit: to those replying I 100% don't agree with all the decisions chrome make, very importantly ad block.
But just survey the actual browser market in the last 10 years to understand Chrome's dominance
