That ’story’ occurred quite a while ago and things have changed since then. One thing that hasn’t changed is that the KHTML developers were not angry at Apple, they were angry at misinformed members of the KDE community who were happy to attribute all the recent work in KHTML to Apple when in fact they were only releasing the source to what was effectively a fork, meaning it often took as much time to understand the changes as it would have taken to implement them independently. What *has* changed is that the Safari team now has a public CVS of their code and commit access has even been granted to non-Apple employees.
