ARM is mad because Qualcomm bought Nuvia (which had their own ARM license) and then started using Nuvia’s designs. ARM says that Qualcomm needs to renegotiate the license in order to use those designs.

Normally ARM and Qualcomm would handle this fairly smoothly, the reason its not happening this time is because ARM and Qualcomm both have growth plans that are increasingly making them direct competitors.

Nailed it. They know they have a leading chip in these designs now, the market is expanding, and whatever licensing fee was negotiated in the past needs to be revisited.
