You are directly using the CPU, you just do not have full access to the entire CPU. There is no userspace ALU that your numbers get crunched on, there is no userspace register file your working set is stored in (actually, they might do that internally, but logically there is no such distinction). You are in a hotel room. Just because you can not stomp around in the ducts does not mean you are not directly using the hotel room, you just have limited access to the rest of the hotel.
