However, Konqueror/KHTML is now dead and we only have a closed source Safari.
I can't fathom your comments back to back.
As I've already stated, any company that may fork a similar project would actually cause more benefit than harm. KHTML died because the web started to get very complex very fast and KDE volounteers couldn't keep up with that pace, unlike Apple employees. Now that the web is a bit more stable, with less standards that are more thought-out (webassembly), it's a lot easier to maintain a web browser. So if tomorrow Microsoft hops in and announces it's intent to fork ladybird, then the latter would not only be fine, but it would probably recieve a new wave of contributors.
