Well, technically, a "throttle" is a device that controls airflow by restricting an air intake passage. (Much as "throttling" someone means squeezing their throat so that they can't breathe) That's how power is controlled on most gasoline piston engines. Turbine engines do not control power by "throttling" air intake, so from a purely pedantic standpoint, the term "throttle" is not correct on a turbine engine. But, if you are truly convinced that this is a important distinction, and you spend any amount of emotional energy worrying about it or seriously debating it, you are probably desperately in need of a hobby or a girlfriend.
