The real hegemony is the Blink hegemony. Google (an advertising company) can pretty much unilaterally dictate web standards. A terrible state of affairs for the web. That's the real issue and using another Chrome reskin is never going to fix it.
For those wondering...:
"Blink is a browser engine developed as part of the free and open-source Chromium project. Blink is by far the most-used browser engine, due to the market share dominance of Google Chrome and the fact that many other browsers are based on the Chromium code."
Blink is a virtual machine. It's like complaining about the Hegemony of Perl
This is the main reason I stay away from Vivaldi; using Firefox is, for all of Mozilla's borderline comical mismanagement, a protest vote against Blink (and previously, Chromium).
