> A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. (GPLv3) Using GNU grep, as GNU grep, and merely aggregating it with the whole, would seem, from the quote above, to not cause the whole to be GPLv3 covered. The only slightly questionable part is the "combined with it such as to form a larger program" portion of GPLv3. Is using grep, to "grep", sufficient to say that grep is "combined ... to form a larger program"? If the answer is no, then yes, the author is simply misinformed.
