There've even been cases of hysterical GNU "developers" thinking they need to re-license BSD-licensed software under the GPL, but it just doesn't work that way.
Actually it's been more the other way around: a developer includes BSD code into his GPL-licensed project, makes improvements (knowing that his GPLed improvements are safe from non-FOSS software, and yes it does just work that way). Original BSD developer throws a public hissy fit because he can't use the new and improved code in his project. Funny how he didn't care when it was happening behind closed doors, but having the new code right under his nose was just too much.
Moral of the story, if you don't want people doing whatever with your code, don't choose a permissive license!
Git is way better than SVN in pretty much every respect except possibly its lack of slick Windows GUI
And even for those who must have a Windows GUI, TortoiseGit is currently being worked on.
