I was at CERN when they visited us with the same type of sales pitch, but I always saw it as an attempt to get people to buy Macs than anything else, specially after how things went with Copland.

The real Apple culture was Object Pascal, Common Lisp, Hypercard, Dylan, Newton, MacApp, PowerPlant, QuickDraw,...

Now they have money and they actually need is macOS, iOS, tvOS and watchOS developers, not UNIX developers deploying code on GNU/Linux servers.
