Green OA is just as meaningless as—-or worse than—-Gold OA. You pay the publisher a large sum of money for the “right” to self-publish the preprint, and they
still paywall it. The vast majority of people will find the paywalled version before yours, and anyway there is no guarantee that your preprint is accurate with the final, published version, so most people will still trust the paywalled version more than your PDF. Especially when performing systematic literature reviews where you need to document the sources of your references.
The current implementation of OA (any of them) is basically a self-fulfilling prophecy: we convinced ourselves that “publishers are evil” and impossible to get rid of, and now we are paying them so that they don’t have to do their job. We basically retired publishers early with an extra pension, all because everyone “wants to believe” in open access. But guess what? This is not disruptive. OA is just as “capitalist evil” as the usual publishing, or even more so. Do you want to be disruptive? The disrupt. Get rid of the publishers. Or at least constrain funding only to not-for-profits for example.
