Agree @BruisedSkies
My child is currently part way through an autism assessment and from my experience I wouldn't say that ASD diagnoses and 'labels' are being handed out all over the place as Sam suggests. There was an incredibly long developmental history form to be filled in, and we are now waiting for assessment sessions with a psychologist. This is through CAMHS.
I also have experience of private ADHD assessment which was also quite an arduous process.
I think those videos are encouraging people not to seek appropriate treatment / medical advice, which is also one of the things they were told not to do by the ASA.
I wonder if the ASA can investigate them again?
