*snort* How about some non-faith-based arguments? There are damn good rational ones for "why source for firmware is generally a desirable thing"; none that I can see for that publicity stunt, but hey, maybe you guys can produce some...
If some luser duhveloper says "this code must work, because my ideology says it must and if you don't share my beliefs, there's nothing I can do, we are just culturally incompatible", the silly bugger will get a rapid and painful course of education in the reasons why solipsism derivatives are BS, why his beliefs don't mean a damn thing for reality and why his faith is not strong enough to avert the well-earned, er, uncomfortable sensations. Why should the same kind of crap be treated any kinder in this case?
Ideology is basically a set of heuristics. The output may be deemed more or less satisfactory by *external* criteria; without those all you've got is a dogmatic religion.
If you have rational and ideology-independent arguments for the tree "freed" in that manner, make those. If not, there's really nothing to talk about.
