The nice thing about podcasts and radio is that you can monologue whatever nonsense you like and act like it is the single truth in the universe. That is exactly what is going on this show. First there is some useful information about sextortion, the forms it manifests in and consequences it can have in real life, that's the good stuff.
Then comes the bad and the straight-out ugly bit. While the speaker starts of with a pretty factual analysis, eventually he slides into a very much opinionated stance against any form of digital eroticism. Don't do ***** kids! Where have we heard that before, right? 
Seriously, if you are an adult having a problem with the fact that people exchange nudes in their sexual discovery journey then that is just your own moral problem, do not project that on the rest of the world please. People have done that about sex, drugs, music, religious believes, cultural habits, and pretty much everything we humans design to entertain ourselves and to carry out our identity into the world. Saying "Don't do that" really is totally random moral stance since what is found to be offensive in your part of the world might be totally innocent behavior where I live and vice versa. 
So, again, because repetition seems to work for Coca-Cola: don't project your own random moral objections onto the world. They are legit, they are rightfully yours to keep. But don't try to push them further than that, because that's just randomly stupid.
