Murof,
Yes, you can actually use present tense. Yes, the meaning is a bit changed, but the difference is minimal.
I have a tendency to explain such differences in impressionistic terms,
so I'll just say that, to my ear, "is used" (in the given context) is a
more remote and aloof formulation, cooler and, as you say, more
factual, while "is being used" is a more immediate and involving
formulation, warmer and more inviting.
In the vaguest, most fanciful way, the simple present informs, and the present progressive seduces!
