Either they are pivoting towards RISC-V or (imo) much more likely it's a Microsoft-style FUD campaign ("Linux - Get the Facts Straight" and other examples) against RISC-V listing all the reasons you shouldn't jump ship towards RISC-V. I think Arm are very worried about RISC-V as it's very possible that a free-as-in-freedom architecture could be competitive. It would only take a big OEM, like Samsung or Apple, announcing they were ditching ARM for RISC-V to really rock the boat. Conversely, it would be a fairly open move for Arm to get involved with RISC-V, though probably welcome.
I'm also seeing a few job ads in my area for companies looking for ASIC/HDL/verification engineers to develop alternatives to Mali GPUs that interoperate with RISC-V. That could be an interesting area to watch. Specifically, I think this could relate to
this story, where Arm has said that they will not allow alternatives to Mali to be used within ARM devices. IMO, that kind of behaviour is just suicide from a business perspective, for a company that has previously depended upon a very open ecosystem to support them. It's crazy to think how much damage SoftBank may have done to a British engineering institution within a decade. There is speculation that SoftBank's CEO is extremely bitter over the Nvidia takeover deal being canned by the UK government, as it may have given them a way out of the mess they got into in the first place over Arm (it could be argued they paid too much for the company).
