Apple's whole advantage is owning the entire stack top to bottom. To achieve that with servers they'd need to develop their own server OS and perhaps app ecosystem on top of it too - that really isn't their focus. Or they could stop at "here's a machine, run what software you want", but that's completely antithetical to everything they've done so far.
