Tensions between Qualcomm and Arm have been escalating in recent years, and the dispute has now reached a fever pitch. Arm is reportedly moving to cancel Qualcomm's architecture license agreement (ALA),

Qualcomm has canceled its Snapdragon Dev Kit, the miniature Windows on Arm PC that was originally supposed to ship in June. In an email to customers, Qualcomm said the mini PC “has not met our usual standards of excellence” and orders will now be refunded.

It's the former that Qualcomm has done with Snapdragon X, so the licence cancellation would apply to custom CPU designs, but not to other Qualcomm chips based on Arm CPU core designs. In other words, the cancellation wouldn't mean that Qualcomm couldn't produce any Arm chips at all, just Arm chips with its own in-house CPU core designs.
