IIRC a lot of that has to do with spammy 'publication mill' journals. If you just look at 'decent' journals, the situation doesn't look nearly as dire.
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.
