so what? Regular users (whatever they are) don't know or care that a mac is unix under there somewhere.
At moments like these i feel the loss of the nokia N900 that was glibc, gtk+ linux all the way down and up. Best phone I ever owned by a margin. Also arguably not a machine owned by apple/goog/samsung/etc whose purpose is surveillance of the schmuck (me) who just paid for it.
Its UNIX influence is a phyrric victory, without any real value as Google can completly replace it with Fuschia at any time they feel like it, and those regular users won't even notice.
