This has little or nothing to do with it, as the antivaccine movement has long shown. Prominent members have access, either themselves or through sympathetic contacts. They’ve long used that access to cherry pick and misrepresent the science. https://twitter.com/bettinaryll/status/1342921143116845061

Open access to primary research and cranks cherry picking or misrepresenting that primary research are separate issues, and, at the very least, more open access will not mitigate the problem of cranks with big blind spots because honest understanding is not what cranks are about.

I’m all for more open access. I do not, however, expect it to decrease the severity of the problem we have with cranks that I described. If anything, it might make the problem worse by making it easier to cherry pick, a risk I’m willing to take.
