On your point 5, “Do not serve as editor, reviewer, or author of a paper in a for-profit journal.”: I often get pushback from colleagues on this one, as some feel that by refusing to review others’ papers in non-open journals, I am harming the authors. I take this criticism seriously enough that I wrote a post explaining in detail why I think it’s nevertheness the right thing.

You do conflate open=non-profit and non-open=for-profit, as your colleague noted. Specifically, your point 5 is aimed at for-profit publishers when I think it should be aimed at non-open publishers (and I suspect that’s what you meant?) Note for example that PeerJ is a for-profit operation — but like you, I use and recommend it, because it’s fully open and provides a good service at a good price. That it’s also (potentially) enriching individuals is not a major negative in my view.
