ARM has extensive IP and know how. They could build up and sell high performance RISC-V IP/cores now and prevent RISC-V focused companies like SiFive from gaining a foothold by denying them revenue and investment. Alas, that would probably have worked better 2+ years ago, there is a lot of movement now. It seems like Intel has realized this. They tried to buy Sifive, but have now themselves joined as a major RiscV International sponsor and are investing heavily in the ecosystem. Of course there is a downside there too, because it accelerates a software and hardware ecosystem transition to a different architecture that can enable other players. We'll see how it plays out
