I'm still bitter at how they murdered KHTML.
(Before someone comments "But KHTML is LGPL!": I know. That's the point. The GPL doesn't have these problems. The LGPL is too weak to be meaningful.)
Murdered? Thanks in large part to the work Apple did to transform KHTML into WebKit, WebKit and its derivatives (like Blink) have utterly dominated the browser marketplace. I have a hard time reconciling your characterization of Apple's action with the facts.
Yes, we know that a certain subset of Free Software zealots prefer preventing non-Free software to promoting Free software.
> What happened wasn't, though.
Why exactly is the creation of a set of F/OSS browser engine cores which have essentially completely extinguished the proprietary cores to dominate the space not “fine”?
Apple forked one in a hostile fashion, and later used it to release proprietary software.
A substantial volume of web browsers, including the largest two (Chrome, Safari), are proprietary software, directly because of this.
It made the WWW less free, and hurt users.
I guess you are the 0.0001% of the internet who consider Chrome and Safari to be proprietary software, when it has an Open Source version freely available.
