this worked for me too! thanks!I was having the same issue with the "not geniune" pop-up, even after many fresh installs following the latest steps. The only thing that removed the notice for me was blocking communication to cc-api-data.adobe.io and ic.adobe.io. This might break neural filters or other things, but it seems to fix the activation issue.
Not sure if something has changed, but this version doesn't seem to install AGMService or AdobeGCClient at all...
