I wish it were a strawman argument.
Chrome is ~80% market share of browsers. Google search is dominant, and pushes Chrome heavily. Google's own apps and platforms push Chrome, and on mobile they ignore user choice and offer to open links in Chrome by default. Google is known to have repeatedly sabotaged Firefox [1]
Google fully dominates web standards committees. Google already barrells through with their proposals with complete and utter disregard to input or objections from other browser implementers.
The web is already given over to Google.
