Report: Arm cancels Qualcomm’s architecture license, endangering its chip business
Dispute goes back to Qualcomm's acquisition of Nuvia in 2021:

Better use Intel x86?
Any other ?

ARM is being stupid and greedy. And advertising it.
The new RPi chip has both ARM and RISC-V cores, two of each. There's a message there: an ISA isn't worth much, and ARM is being stupid and
greedy.
x86 is a clumsy dinosaur. The future is many-core RISC.
Arm has an enourmous debug infrastucture. Each risc implemenation
nearly cook there own soup. A core without debug infrastructure is
less attractive...

They also have a boatload of predesigned/debugged IP to offer
to their licensees. And, a broad base of developers and fabs
already experienced, there.
The trend is pretty obvious -- MCUs are moving more and more
towards the market that was previously the domain of CISC CPUs.
The needs of the ever-shortening (per unit-feature) development
cycle make it clear that the processor has to do more for the
developer. Witness the number of "memory protection" schemes
that keep popping up. The more fine-grained they are (i.e.,
don't just protect TEXT vs DATA but, rather, *me* from *you*!),
the more advantageous to the developer.
[Think PoLP, KISS, encapsulation, information hiding, etc.
Even if you are the sole developer, being able to protect
one task from the actions of another is a HUGE reduction
in debug time: "Hmmm, why this bus error? What the hell is
X trying to do in Y's domain??" Trust me, it is *so* much
easier to get a finished piece of code when it is the ONLY
thing you have to worry about!]
I love the ARM cores ! Especially the ST implementations and
peripherals.
As for noise, at least ST has a spread spectrum option for
its PLLs if you wnt to enable those.
