I don't really see how this follows. Fixed length instructions are a well known and highly desirable property for instruction decoders (at the cost of some density), which has been known about and done since the first RISCs. And ARMv8 is basically just a warmed-over RISC with very little new or innovative in there. It's just an ISA.

ARM Ltd is basically rent-seeking on keeping the ISA proprietary, same as Intel and AMD do. Sure it's a highly specialized and very impressive task to make an ISA, but not to the value of extracting hundreds of millions of dollars ever year. If ARM gets upset because someone wanted fixed-length instructions standardized in RISCV that's really the height of hypocrisy.

ARM never said that.

ARM makes money on selling ARM design, not from their ISA licensing.

Someone did.

That's not correct, they make money from ISA licensing. That's called their architectural license, and that is what is being canceled here.
