What do you mean? Anyone getting SoC money is hardly in a position to wine. Google is doing charity/good will work, and if it doesn't fit your ideals so then don't bother. If you wanna give away 4500$ you're allowed to put up whatever guidelines you wish to. Now it's google, so let them do it the way they wanna do it.
As long as this brings usable code I'm all for it, be it FreeBSD, Haiku or whatever
