Context (for those who might not be in academia): many academic publishing companies (like Elsevier) charge exorbitant prices for researchers to get their papers published as open access. Meanwhile, none of these researchers actually get anything in return for it (except for major street cred if their papers get highly cited)
And what's worse, when there were some big negotiations on open access a few years back, the agreements were wholly insufficient and still disproportionately enriched the journals at the expense of researchers; "Gold Open Access" journals will publish the research unpaywalled, so anyone can read them, but will charge absurd "article processing charges" that are often thousands of dollars, shutting out researchers with less financial means (such as those in the global South or independent researchers).
Fortunately there is a growing movement who gives a fuck about actual open access; Diamond Open Access research involves no fees to either the author or the reader. This is how it should be.
The future is here, it's just unevenly distributed
