AMT/vPro is apparently not for servers, and likely operates on the system NIC. The first rule of out-of-band management interfaces should be "use a physically-separate interface", which is unfortunately frequently broken (by one vendor when the procurement specified a separate interface).
The devices which have the feature enabled are probably business devices and the feature is used to manage them. Business devices are good value targets, I guess.
Edit : I guess those devices will probably receive the fix, since they are managed
