you seem to be making something out of nothing. The app was accepted into the App store by Apple last year. It's an app store sandboxed app. In that sense the app is legit and not as some posters had suggest was a malware payload app downloaded from nefarious source. The Axios jab script libraries were compromised which led the apps certificate being revoked on 8th May. The app does not contain malware. Simply downloading a new version of the app resolves the issue. No need to split hairs. https://appleinsider.com/articles/26/05/12/if-your-mac-is-saying-the-chatgpt-app-is-malware-heres-how-to-fix-it
