Elsevier is a despicable firm, but their journals are hardly publication mills, so not sure that response holds water.
The Wikipedia article has a long section of criticism of Elsevier: https://en.wikipedia.org/wiki/Elsevier#Criticism_and_controv...
But that said, I don't know of any author that wouldn't give you a gratis copy, oh, ok, maybe an old 'draft' that is 'close' to the publication.
