I understand your rules and it is truly disappointing that the CFO was unwilling to answer your questions.
I believe the "paranoia" from AYSI goes back several years to when they were still a reporting company and they went under investigation by FINRA. FINRA believe there was a release of non-public information, though the investigation never turned up anything.
I think as a result, the company has moved to the extreme side where they don't answer any questions, even if they are not material non-public information out of an abundance of caution. Have you tried reaching out to Andrew Kostecki who is based in North Carolina?
