Maybe they're greedy or maybe they see the long game is that their architecture licensing business is in serious jeopardy from RISCV. So, if you can't beat em, join em.

Maybe they'll eventually make their own RV core designs too.

I am not a deeply technical embedded person, but I actually don't think that would be the death of ARM: my understanding is that they develop a lot of SoC-level interconnect/fabric standards and IP as well. After all, you have to do a lot of work to integrate your ARM cores into an actual platform...
