This is not a violation of the GPL. Those distributors (almost all of whom are commercial businesses selling free software distributions and related services) are trying to reduce their own legal risks, not to control your behavior. Export control law in the United States might make them liable if they knowingly export software into certain countries, or if they give software to parties they know will make such exports. By asking for these statements from their customers and others to whom they distribute software, they protect themselves in the event they are later asked by regulatory authorities what they knew about where software they distributed was going to wind up. They are not restricting what you can do with the software, only preventing themselves from being blamed with respect to anything you do. Because they are not placing additional restrictions on the software, they do not violate section 10 of GPLv3 or section 6 of GPLv2.
