It was probably intended as comedy, just like my reply. Wait for the Mac comedians next!
Well, that would be silly -- any OS requires updates from time to time, to patch bugs and add new features. All my machines (and I have Windows, OS X, and Linux) push updates from time to time -- well, not the Linux box, but that's only because it's Fedora Core 14, which is essentially end-of-lifed now, but my museum piece of hardware running it can't handle a later version; just fine for Firefox and OpenOffice, though, which is all I need it for. But it got regular package updates up until the point it was no longer supported.
