Honestly, this kind of discussion comes up very often, but it is really difficult, if not impossible, to get out of this situation via bottom-up action. Top-down measures for governments are pretty much needed for any meaningful change.
(1) Actually, to be more precise, all my papers are already open-access, but many of them are in for-profit publishers that charge the author thousands of dollars to publish open-access, which in my view is also a parasitic model and a scourge for science like paying for subscription. The specific thing I've thought about is not publishing in any for-profit publisher at all, but anyway the shackles that keep us tied to publishers are the same in both cases (modulo whether you have funding to pay publishing charges or not).
So you can still continue to publish in journal, while the research is also still freely available. Usually you are also allowed to share the published article via email, just not put it publicly available on your website...
Not publishing means you are not producing which means not being hired after.
It is difficult to get position, so if you want to stay in, you need to keep your record perfect.
