Elsevier has a nice summary at [0]. At the bottom there's "Publicly share the final published article". It's "YES" for Open Access and "NO" for subscription (classical) model. There's a rather detailed "Scholarly Share" which allows sharing with researchers, but not to any researcher, as I aforementioned on top.

The paper was not bad to begin with, but the edited/revised version painted a more complete picture which shouldn't be possible without a set of external reviewers.

The more we all do it, the more expected the practice becomes and with any luck, these money-grubbing journals will take note and start offering copies at a minimal fee or time-limited access.
