A ton of JavaScript frameworks that are using are mostly MIT.

All the BSD kernels, OpenBSD, NetBSD, are of course BSD.

And so it's a philosophical change on how you want people to contribute back.

Basically.

So you have to realize that you can always go from more permissive to less permissive, right?
