Of course, and Apple's ISA is targeted towards the People Who Buy Macs industry. By not making it available to datacenters, they are supporting other CPU vendors in the race to catch up. It will help AMD a lot in their bid to catch up that all investors can see that Apple won't be competing with them.

This is by far the most charitable characterization of this monetization scheme I've seen so far.
Some would argue this is actually in place to ensure that purchases go directly through Apple each time (i.e. a one-to-one of customers to hardware purchases), rather than through a cloud provider who may purchase hardware once and allow thousands of customers to access it.
c.f. Apple's restrictions on subletting use for no less than a single day per "machine".
"Apple is extracting value at monopoly-pricing levels" == "Apple is leaving tasty treats on the table to lure competitors." They're the same statement but phrased in different ways. Any price above the equilibrium lures competitors - that's how markets avoid monopoly pricing, in the absence of external factors that protect the monopoly.
