My fundamental problem with this author is his massive conflict of interest. He's not an outside observer but rather a Chromium engineer, former Google employee, current Microsoft employee. He talks about "competition" and "competitors" while basically ignoring the monopolistic landscape of the industry and the role of his own employers in that monopolization. Nobody has clean hands here, not Apple, not Google, not Microsoft. I don't see any of them really acting in the best interest of consumers. Let's not pretend, for example, that Chromium doesn't push a bunch of shit that consumers never wanted.
Progress would be breaking up this triopoly, not allowing Blink/Chromium to dominate everything.
The web "standards" bodies are a joke now because of the dominance of these few companies over web browsers. I don't even want to hear about standards anymore. So-called standards now are just the monopolists coming to agreement among themselves. All we have here is the employee of one monopolist complaining about another monopolist.
As far as I'm concerned, the web standards should be so simple that a little indie developer could write a full-fledged web browser. But people like the article author want web browser engines to become entire operating systems, which in effect excludes almost everyone from writing a web browser. That's not openness and freedom. It's inherently monopolistic.
