The incident you mentioned is yet another piece of fallout from Rochdale, but if you look closely the offences mentioned are from 20 years ago. I don't think that should be used to talk about the present. There is a lot more safeguarding these days.
The main negative factor is the press, responsible for both "opinion management", doomerism, and sensationalist demands to Do Something in a way that doesn't help. The Online Safety Act and Brexit are both victories for the Daily Mail that are losses for the rest of the public.
