Intel doesn't need to buy anyone or take any license to start making RISC-V chips that compete with Apple's M1. And in fact SiFive really can't help Intel with this as SiFive is just in the process of shipping RISC-V chips similar in complexity to Pentium (but at higher clock speed), and is preparing chips similar to Pentium Pro (OoO) or Pentium II (OoO with SIMD)
