Imagine you're a state-level intelligence agency, you often can force ISP located/headquartered in your country to obey, and it's probably easier to infiltrate some small-ish out-of-country ISP than an Apple/Google/Amazon data center. It's not necessarily that the ISPs will want to break into equipment, just that they are the weakest link bad actors can use to target Apple/Apple Customers.
