Oh yeah, they emailed me as a Google Workspace administrator and went "FYI we're launching this and we're leaving it turned on and forced-opt-in by default, byeeeee!". Even with Gemini off across our entire tenant.
Bonus points that they've broken additional bounds and now advertise in Google Workspace products. Now I get ads within all of the products begging me to upgrade our Workspace tiers :\
Opened a support ticket about the advertising and was told to kick rocks.
