The irony is that Chrome’s rendering engine was a fork of WebKit, which was a fork of KHTML, a free and open source rendering engine created by KDE for Konqueror. They basically took something free, used Microsoft’s “embrace, extend, extinguish” tactics on it. Now KHTML is vestigial, only found in the UserAgent string.
But we could have had a truly free open source cross platform browser with Konqueror.
Best we have now is Firefox, but the bulk of Mozilla’s development funding comes from setting Google as the default search. So it is also hijackable.
In circa 2003-2004, it was as close to on par with browsers at the time as it would get. I think the WebKit fork did damage to the momentum. By 2008 with KDE4, the rework that split it and Dolphin into to products was basically the final nail I think, as development work effectively stopped.
