Too bad they have to use text to make their point. It would essentially reach zero people due to rules (https://www.facebook.com/business/learn/lessons/how-to-adher...). Then there's personal attributes (https://m.facebook.com/policies/ads/prohibited_content/perso...). Then ads that do not sell products/services follow murky rules, and talking about Facebook itself is usually prohibited. (edited from: because the rule they're actually breaking is the "No Text" rule in Facebook ad creatives.)
Is there non-symbolic imagery that they could have used to say the same thing?
Perhaps they should have retained someone with this kind of creative experience.
Looking critically, the most narrow and serious obstacle to advocate for privacy is storytelling.
