"KTHL is not GPL, so Safari and Chrome are proprietary" gets the consequent wrong. Apple did not decide to fork KHTML and then pick a license. If KHTML were GPLed, Apple would have forked a different project, or perhaps even started from scratch. The end result would have been the same.

You're making a baseless assertion. Apple ships an enormous amount of GPL software with OS X. It makes no sense for them to write an entire browser from scratch just to avoid the GPL when they're perfectly happy shipping bash, emacs, samba, etc.
