what do you mean "control the internet"? Microsoft for all intents and purposes controls all documents across the globe with their Office suite and it doesn't mean you can't write "hitler" in your document. I mean, c'mon.
That analog doesn't fit at all. The internet is public infrastructure, akin to roads or utilities. Not just document writing software.
Your web browser is your primary gateway to the Internet, which is a fundamental part of our daily lives now With Google dominating the vast majority of the market (not just through Chrome but also Chromium) they dictate the mechanisms used to access it.
Google Chrome is already the defacto standard. Web developers design sites with it in mind first, everything else is an after thought. If Chrome decides to implement a feature that impacts user access or website design, everyone just has to go along with it.
Look at the "Web Integrity API" fiasco from a while back. Google was basically proposing that websites be able to block access if they don't like something about the clients environment. That is entirely antithetical to a free and open Internet, and had they decided to move forward with it the rest of the web community would have had no choice but to go along.
