I don't see any real reason, apart from ire for the GPL, for Apple to insist on attaching its EULA to the
app (as opposed to the use of the platform, say, which is GPL-compatible), for a free-software app where the author doesn't want to add a EULA, and where the source code is freely available. The purpose of the EULA for proprietary apps is to ban various kinds of reverse-engineering/piracy, which is a pointless thing to ban if the source and app are given away and the app author doesn't care about reverse engineering.
It seems perfectly reasonable to me for a software author to say: I give this app away for free, and you can redistribute it, but you can't attach an EULA to my app if you do. If you, for some reason, are so pigheaded that you insist on adding no-reverse-engineering conditions to my app, which has no actual effect because the damn thing is open-source anyway, I'd blame you for the pointless ideological policy.
