Unfortunately the article is behind a paywall… But I am curious, does this mean there won’t be any new Cortex-Mxs microprocessors?

The summary says that Arm wants to “enter the chip design space”. They weren’t doing this already?

And, is the prospect of a proprietary chip an exciting tease when pitted against an open standard one? I am excited about RISC-V microprocessors precisely because they rely on an open standard, so I am curious to see what their angle here is. I tried to find a non-paywalled source but I couldn’t find one.
