Maybe it would be better for them to enter the Risc-V market. My working thesis is that SoftBank had milked the Arm cow dry. That is why they took it public to pawn the dregs off onto the retail investor. Paying for an Arm license is wasted money and akin to paying for an OS these days.

The demand isn't there for the RISC-V product. AMD is exploring this space[1][2] but they aren't bringing them to market because sufficient demand isn't there yet.
This is a "why not both" strategy: ARM has the market share whereas the RISC-V ecosystem is still being built up. Once you have a RISC based chip, it's not nearly as much work to change to another RISC ISA.
