Similar arguments were tried in the early days of the telescope in the 17th century, asserting that what was being observed could not be trusted due to the mediation of the lenses (early telescopes were generally refractive). While imperfections can limit and govern the information available via telescopes, there is no reason to believe that said information is false or somehow governed by anything other than physical phenomenon. It was, and is, the height of sophistry to make such an assertion.
