I think federal regulations should be created to require two things: 1. Anyone who makes a browser is prohibited from advertising it on other sites owned within the same corporate hierarchy: no lying to YouTube users that they will have a better visit if use Chrome, etc. 2. Any organization which has a majority stake in a browser has to test every web app in every browser with more than 0.5% share, and has a time limit to fix any compatibility or performance issues except those caused by a browser not having good support for W3C standards. The idea there is preventing stuff like the long period where YouTube used a Chrome-only web components draft rather than the standard version Firefox and Safari implemented and served them a dog-slow polyfill instead but still allowing them to tell Apple that feature X doesn’t work well because the implementation in Safari needs to be improved.
