Those shenanigans from Intel killed off PA-RISC, Alpha and Clipper. SGI were a bit more canny, but still got sucked along and almost took down MIPS. The world is a worse place for Intel, but we have to look forward.
If Nvidia tried to squeeze ARM licencees, that would just force adoption of RISC-V. Given Nvidia is a RISC-V user, they know this.
