The only place I see Chrome is the objectively better product is when using google services, so your monopoly argument somewhat falls apart.
Chrome has the highest market share of internet browsers ~this side of the great firewall~ worldwide (just checked, still is the case in China today, assumed it changed)! Far worse has been done to companies with less control over their respective markets.
I am being a bit facetious when it comes to features though, fully admit, FF is better in getting a few of those, and don't deny history especially with Firebug.
Wake me up when the government finds the gumption to break up any of the monopolies that are begging for it. Google is but one of dozens that should have been broken up before now.
Technically even Bell didn't lose a case, it broke up "voluntarily" before that happened.
