I don't have such a problem with browser makers putting their own ideas into their software. If Google wants to put a Flutter runtime into Chrome, great, go ahead. Where things fall apart is when they prioritize these projects ahead of supporting standards upon which they agreed. Microsoft was free to build and support VML back in IE days. The issue I had was that they refused to support SVG which WAS A ratified standard. So Google creating experiments is just that. They're free to build these, evangelize them and bring these to WHATWG, CSSWG or TC39, or whatever other governing body they'd like. They aren't "creating standards" if these governing bodies do not adopt their experiments.
