They are letting others use their API.
As you can find in several my posts, "they are letting..." is the only known statement. Can you as a customer get the API? What means "a partner" in terms of agreement?
Sure they "are letting", it will be 2x more fanny in case they put title "Standard" on something they never show anyone
But in case somewhere in the license there is simple statement "to be used with NI products only", that was with "the standard" then. That means the standard is NI INTERNAL (equivalent to useless for anyone without NI keyboard/controllers, my guess the majority of users).
