Arm and Qualcomm have been in a war for quite a while now over Qualcomm's Oryon cores. These cores are used in the Snapdragon X series and, now, the Snapdragon 8 Elite. To give a brief overview of the situation,

Any company that makes Arm chips must license technology from Arm Holdings plc, the British company that develops the instruction set. Companies can license the instruction set and create their own CPU designs or license one of Arm's ready-made Cortex CPU core designs to incorporate into their own chips.

Arm Ltd. has notified its licensee Qualcomm, informing the company that its architectural license will be terminated in 60 days — the agreement that allows Qualcomm to manufacture the Oryon CPU cores at the heart of the Snapdragon X Elite chip and Copilot+ PCs.
