I missed your response yesterday.
> You've got your history wrong.
You're right. I was careless there, however I knew about WebKit's root, and I use a custom fork of WebKit for one of my own projects... And I never remember which version of GPL and LGPL imposes what restriction, so what I meant by pure GPL was the most restrictive kind of GPL.
> There's no evidence that without KHTML they would have done a "proprietary browser from scratch."
No, there isn't. But Apple is a company that doesn't do open source projects unless they have a very good reason for that. With the current hindsight, yes, It's clear that using an open source browser was the best choice for them. But at the time, no one knew that WebKit (and Chrome) would be such a success (with the huge adaption of Chrome on desktops and Safari on iOS's). That's just the way they did and continue to do their business. So while my assertion was just a guess, it's not a baseless one. We can never know.
> ...the license does not seems to affect the amount of feedback or amount of uptake.
No comment on that, because my experience is far less than you. I just feel that it must be easier to talk a non-technical manager into using a BSD/MIT/Apache-licensed codebase than a GPL one.
Again, I agree that my comment above was sloppy and I should've made my points clearer and spell them out as my thoughts, not facts.
