You understand that in those chats, Micay had been the victim of ongoing harassment, perpetuated by Rossman and Calyx leadership, which culminated in doxxing and then a SWAT attack which is a threat on their life.
Please provide evidence for that. Also why was he a "victim of ongoing harassment perpetuated by Rossman" and Micay never mentioned that in the chats in the video? Did you even see the video? The only accusation in that chat was that he commented under the Techlore video. Everything after that was orchestrated to destroy Rossmanns reputation.
Did you even read your own link? Four server CVEs this year is close to nothing. Windows and Linux patch like 40 a month. Also none of those vulnerabilities would provide unauthenticated access to any data. Pretty much 99% of all published CVEs only work if you already have some access or privileges on the system.
