With Google's latest move to lock down the web (Web Environment Integrity) I'm reminded once again of all the folks who've earnestly tried to assure me over the years that the greatest threat to the open web is actually Apple not allowing 3rd party browser engines on iOS.
@nicklockwood Chromium is powered by WebKit, though. Same engine. Firefox's Gecko is the only competition at this point.
@jimmythomas @nicklockwood Google forked WebKit 10 years ago… they are quite different now: https://en.wikipedia.org/wiki/WebKit#cite_note-12.

@alwillis @jimmythomas yep. Plus it never shared the same JavaScript engine, even from day one.
