Quoting an anonymous Twitter user (got harrassed for these statements):
"Safari is buggy" is a valid criticism.
"Safari is behind Chrome in features" is not a valid criticism.
Never forget that the browser vendors, including Google and Apple, seized control of the web from the W3C. These few companies have too much power over the web, period.
Imagine a small company trying to write their own web browser from scratch nowadays. It's just not possible! The web is so complex, there's no choice but to adopt one of the few existing browser engines: Chromium, WebKit, Gecko. That's it. The competitive landscape is bleak.
"Everyone has to adopt Chromium" is exactly Google's plan.
Who controls the dominant browser engine controls the web.
@xplore It kind of did! Mozilla Quantum was all about swapping Servo components into Gecko without regressing standards support.
I don't believe Servo's still active...
@alcinnz It's still under development as there was a commit yesterday but not at Mozilla but it's now supported by the Linux foundation.
But yes it's 10 years that it's under development so I think your question is still valid as it's clearly over complicated to build a web browser engine!
