For whatever reason, they keep finding people with hot takes about porn but who don't actually study porn effects, instead they hear something alarming and they decide to echo it.
In fact, I don't agree with everything that Dr. Tenbergen says, but at least she actually took the time to do a study, and has some years of experience. If she says something interesting, then I might listen.
But, the "AI ethicist" or the "image analysis guy" is not much better than consulting Gary the computer technician about something he hardly knows about.
If someone actually studied it, and they had a bad take, maybe assuming too much bad, then that might be one thing, but you have these people who don't actually know a whole lot (and haven't touched the field) who get consulted as if they have an defining opinion on the matter.
