Google Ads Introduces Auto-Generated Advertisement Tool Using Generative AI

This was talked about back in May, however, it seems like it may be available now.

To me, the optics of this are bad as an advertiser.

Google has access to my creative assets as well as click through rates and other data...

Is their model using learnings from me to help people bidding on the same keywords as me?
