Because the original was actually Acorn RISC Machines. They might have as well gone on to become "Acorn", well in line with Apple, which they power nowadays to a large degree, and which they might power to a much larger degree in the near future.

They were Acorn at that point. That's why the CPU was called Acorn RISC Machine (singular). There was never any company called "Acorn RISC Machines".
