I don't think what you're posting is inconsistent with the observation the person you're replying to made -- Apple is hostile more specifically to GPL 3, which a lot of companies seem to be (rightly or wrongly). IIRC, a lot of GPL-licensed stuff that came with OS X, like bash, just stopped being updated by Apple when it moved from GPL 2 to 3; moving to zsh lets them keep their default shell up to date while also keeping whichever execs/lawyers have decreed "Thou Shalt Not GPL 3" happy.

Also, IIRC, Apple doesn't have a policy of prohibiting GPL-licensed software from being in the App Store, but rather, the FSF's own interpretation of the GPL is that its terms are incompatible with the App Store's terms.
