There are entire categories of ads that operate on insecurity, they just don’t come out and scream “this is because you’re insecure” as that would make for bad copy. E.g. you think adult diapers advertise on anything other than insecurity (even if that insecurity is well-founded)?

Also, GP was talking about enterprise (B2C) and ads for B2C are pretty scarce in consumer-focused spaces. Insecurity, FOMO, etc is absolutely used to advertise to people in middle management on up.
