What you call chrome skins isn’t a thing, people are building softwares on top of Blink, the rendering engine used by Chrome. The issue here is the risk of ending with a single rendering engine for the majority of the browser market, a diversity of engine ensure a good respect of web standards, that has nothing to do with privacy or security.
When you say “they just replaced IE”, that was >10 years ago…
What.
The point is that the fundamental problem is a company in a monopoly position throwing their weight around and/or keeping their product stagnant “because they can”, which is also a function of power. This is the “authoritarian government”.
The police part is referring to people thinking of specific IE6 technical issues “as the problem”, when it’s just a symptom of a larger problem.
Microsoft treated web developers badly because they could. Google will abuse the whole world in the same way now that Chromium has achieved near total dominance.
Then there's the relentless parade of "alternative browsers" that are just chrome skins - a period IE also went through - that intentionally try to trick people into believing they're not just using chrome but with less security engineering, and more scams.
