ARM likely had no intent to apply this 'all-or-nothing' strategy to any other licensee, given none of the other architectural licensees are likely to be acquired. Nuvia was somewhat unique in that regard. And the need for ARM's approval to transfer Nuvia's architectural license gave ARM the opportunity to force concessions from Qualcomm.
Precisely. Also I can see the Nuvia license being structured to suit the Nuvia situation - perhaps low upfront fee and higher ongoing fees plus lots of assistance from Arm. Then Qualcomm tries to get out of paying the higher ongoing fees by selling Nuvia cores under their license.
