There is a lot of stuff behind the scene you don't know. You statement about "other companies" is completely wrong.
I have watched many discussions and updates by the work-groups, and nobody came forward.
And why are they afraid to come forward? If this is so important then shouldn't there be an effort to convince the community?
So sorry until I see something other claims like 'there is a shadow cabal of unhappy companies planning a takeover' I'm not gone buy that this is widespread movement.
Rivos came forward. They (kindly) told Qualcomm not to put words on their mouth.
Rivos is, of course, totally fine with C.
