The article is probably describing RISC-V as growing in popularity, not number of instructions.

The distinction between "reduced" (RISC) and "complex" (CISC) is more philosophical than "number of instructions."

Even as the RISC-V specification gains new instructions, the modular design of the architecture is specifically designed to allow implementations to pare down to just the subset they need.

RISC-V is extensible and keeps developing new official extensions that add more and more instructions. The RISC-V baseline doesn't even have integer multiply or divide!

My thoughts exactly!
