How does that help anyone? Firefox only survives from ad revenue from Google. Apple had some motivation to keep up with Chrome to a point. But wouldn’t be motivated from competition from Firefox. Apple is much more motivated to improve its own platform.
Microsoft definitely doesn’t care about the web or even its PC operating system much.
So now, no one is pushing the web forward. But Apple, Google and Microsoft are still motivated to improve their own platforms. While I personally think the modern web is a cesspool and I am okay with that as a user, I doubt many on HN who care about the “open web” feel that way.
As a developer, I haven’t touched the clusterfuck of modern web development for over a decade.
