I think this post sums up their attitude pretty well:

Basically, the OpenBSD crew are fine with evil corporations using their code and making it proprietary, because they'd prefer that to Apple or IBM writing their own shitty implementations.
But, at the same time, they dislike GNU and the GPL because of a difference in principles, so to take OpenBSD code and sublicense it under the GPL is fine as per of the terms of the license, but it's a dick move.
