No. Someone is (passively) failing to provide free access to their own contributions to those journals, and that someone is the author of each and every article appearing therein (with the exception of a growing number of physicists and a few other disciplines at last beginning to do the right thing!).
I would like to believe this, but my imperfect memory of the publication contract I got from CACM seems to say that authors are not allowed to do this if they sign such contracts. (That is part of the reason I always insist on renegotiating them.)
