If Google wasn’t such a trash company and using chrome to drive more revenue by farming data and preventing adblocks then no one would have a problem with chrome.
Google at least gave you the option to do that.
Not sure if Google voluntarily gave users the option. Google was forced to give users the option since Blink is a derivative of the LGPL-licensed WebKit, which is itself a derivative of the LGPL-licensed KHTML.
An argument can be made for open-sourcing the frontend of the browser. However, even the WebKit codebase has a test browser that runs on Windows (despite Safari dropping Windows support over a decade ago). This would have been present in the Blink codebase even if Google decided to keep the Chrome frontend proprietary. So people would still be able to embed "Chromium" into applications.
It’s baffling that you’re unhappy with companies wanting you to pay for their product. Yes Netflix increases their prices and wants to prevent you from sharing your account, but they’re not scanning every single email you’ve ever received or making the web worse for everyone to collect more data about you.
