1) it's not a "technicality". It's a federal law and the law is very clear and delineated. "Many poster" violating HIPAA, as the post above says, are simply not violating HIPAA. Are people violating his privacy? Perhaps, but that is up to Cordy to decide.
2) We don't know this. Perhaps this information originated from Cordy himself. In that case, no HIPAA violation occurred. Nevertheless, the point still stands, "many posters" here, as clearly written in the post above, are not showing a "blatant disregard for HIPAA". There is only one single poster here whose motivations are questionable. The rest are just people being people on the internet.
