once noone replies, i'll share my understanding, but i didn't have any experience with that i think because they can (demand money from anyone due to intellectual property).

i'm not sure if anyone have challenged it. or i may be wrong and basically they can enforce their demands based on usage of their brand only. or noone really has needed that, because everyone is happy to collaborate with the arm company in some other areas besides licensing, so this very fee is nothing for them.
