The ad [1] takes the user to a website [2] where they're prompted to join the beta to test a ChatGPT browser extension that helps create Google Ads. The website links to a github repo [3] with instructions on installing the extension in developer mode. On quick glance, the extension appears to log clipboard and keystrokes. Please correct me if I'm wrong.
[EDIT] The Twitter ad [1] has over 7M views since June 27, 2023.
