You're right of course. All I meant by my post was that if I were looking for GPL code, I'd check the apps before I'd check the OS. I also wanted to tell the story about the tapdancing; it was really fun to watch, and rather instructional.

I would be amazed if any code were lifted and placed into IE. I would be a bit surprised, though, if when MS implements something that's already been done already, and they can get source to look at, they don't look. Which is OK.
