I can't believe I'm defending Google, but all of those things are on their own properties. Aggressive and user-hostile, yes, but they're not abusing their ownership of the browser to modify their competitor's site.
In comparison, Microsoft implied in their advertisement that their browser is safer than Google’s because it has the “trust of Microsoft.”

I don’t however think there’s a strong argument to be made that MS is modifying the website unless they MITM it. It’s well within their right to make their browser display something they want it to in a specific situation.
