"Holding the web back" lol. What the web is today, is coming straight out of Google's playbook, with WHATWG just a miniscule puppet organization consisting of Chrome devs promoting whatever Chrome does as standard. It's a scam to subvert what once was the web into a monopolistic tracking network and a 20 year project to morph a document viewer into the most absurd, power-inefficient, and clunky app platform imaginable that still can't do most anything that you'd want a smartphone to do, such as phoning. The narrative that big brother Google protects us from evil proprietary vendors somewhere lost its credibility; today, we need protection from Google more than anything else. Almost all new HTML5 APIs and even CSS can and will be used for fingerprinting so need to be rolled back or switched off anyway.
