IMO, this Instagram page is not controlled by CYDY itself, but an investor. I cannot prove that, obviously, but I don’t think NP or anyone at CYDY right now has the time or energy in between world wide COVID19 efforts, the BLA filing, and cancer trials, to make an IG account and update it.
Another hint is the name, “cytodyn_updates”, which indicates it’s not the company’s official IG page.
