> So what would have to happen would be for everyone who ever contributed to VLC to say, “Okay, I’m chill with BSD,” and the code contributed by anyone who refused to do so would need re-written e.g. in a cleanroom to avoid copyright infringement. :-/

And since one of the VLC developers has already invoked the GPL to prevent the distribution of an iOS version, the same developer would probably block BSD relicensing for the same reason.
