Censorship is wrong. Every rational, adult human being should have the fundamental right to their autonomy, without third party intervention, with full awareness of the laws that apply to them.
If they decide to abuse that freedom and awareness by accessing illegal content (even CSAM), then they are taking the risk of being discovered, prosecuted, and punished accordingly. And, in many cases (like CSAM), I hope they are caught and punished.
Regardless of the outcome, it still starts with the freedom for that individual to make that decision for themselves.
