Chrome used to work well. But now it’s literally the new IE. It forces itself to people because so many web devs only test on Chrome for compatibility. Add on to people have their habits built up through time, people use Chrome now because it’s Chrome.
And we are entering the new dark age of internet, where the whole internet will be Chrome-based. Once iOS is opened for other web engines, web developers no longer has a reason to test compatibility with Safari. They would just tell their visitors to install Chrome.
Google’s own services already don’t work with other Chromium based browsers. Eg Google Docs, Sheets, etc don’t work with Brave. I have to use Safari, but that’s because WebKit is enforced on iOS, so Google would have to support it. Once that restriction is gone, Google can simply drop Safari from their supported browsers.
