Cory's posts on Elsevier are consistently disappointing. I expect a professional published author to demonstrate a closer familiarity with field of publishing.
This creates a vicious cycle, where the best publicly funded research is published in Elsevier journals, which then claims ownership over the research (Elsevier, like most academic journals, requires authors to sign their copyrights over, though it does not pay them for their writing, nor does it pay for their research expenses).
This is not how copyright works. Copyright applies to the published article, not to the underlying research. Further, Elsevier publishes close to 17,000 journals. All of these have their own individual copyright policies. Many of those journal are not even owned by Elsevier, and so copyright is instead negotiated the third parties that do own the journals. Many Elsevier journals do offer Open Access, and many more are now offering authors Creative Commons licenses.
Full disclosure: I am the managing editor of a health science journal published by, but not owned by, Elsevier.
