You mean the card threatening his children he wrote himself? Or do you mean the fact that they let their 3 yo wander around in the garden alone and vulnerable? Maybe Emilia being used on weirdo sites? Or maybe the fact that he shows us his children's school grounds and their uniform and logos, so every sicko can go and pay them and every other child there a visit?I'm sorry but don't you remember they have had death threats and people trying to find where they live. I would want to have cameras around my place too to feel safe people are really mean to them.
Or maybe just the fact that he chose money, celebrity and an easy life over getting an actual job to protect the privacy, integrity and safety of his children? Jonathan wakes up every single day, making the conscious decision of unnecessarily putting his children's safety on the line for the life it offers him. Don't invite danger so openly into your life and then moan when you have to live in fear.
And by the way, those security cameras are mostly for catching vlog footage and "watching" the kids without actually having to get off your arse.
