The point is that these women are being hired effectively as paid advertisers for products that are not allowed to be advertised on the platform.
Now, you can argue about whether those restrictions are good or not. But nonetheless Facebook/Instagram and Twitter won't take money for "gun ads". Yet they are running what are quite clearly gun ads anyway.
Or it could be some kind of negative-submarine article. (I've seen guns on instagram, but haven't seen so many "gun influencers" selling products).
Ugh, this is a really off-putting joke. I remember when gun ownership wasn't so hand-in-hand with extreme right-wing views, but this along with everything else seems to be increasingly polarized. Look at how the NRA has changed over the years for one good example.
