Define "own servers" because this discussion is about controlling the entire stack, and eliminating things like ME or PSP. FANG runs on AMD/Intel, so they don't own their own stack. They have to contend with the AMD/Intel product.
Buying a beige box to put an intel chip is not "your own" servers in the context of this discussion. I'm not sure why you're so rude and confrontational here. We're discussing how Apple has top to bottom control in its consumer devices, not some weird discussion about datacenter packaging. Servers run on AMD/Intel and as such are stuck with the elements of those platforms AMD and Intel dictate. That's not having the entire stack to themselves.
