Governments would rather censor the whole internet before putting people who have credible allegations of sex crimes against children under investigation and in handcuffs when appropriate.
There's no conspiracy here; the UK government is not wanting to censor Wikipedia (honestly!) - what this really is is the consequence of poorly written legislation introduced at the behest of tabloid-newspaper-supported children's online safety nonprofits - they have a very high level of public support (from parents stressed-out over how bad the Internet is thesedays, which is fair enough!) - and this translates into strong political support, which leads to MPs actively avoiding listening to technical experts and other opposition voices because no-one wants the Daily Express to call them out as being on the side of (vague and nebulous) Internet child sex predators (or "the paedos" for short, in UK tabloid speak).
...and none of this has anything to do with Prince Andrew et al (because that's in real-life, not on the Internet).
It's the exact same process that lead to the 2010s IWF/Cleanfeed/Wikipedia block over controversial 1970s music album art.
It's idiocy and fear of a rabid public, not a conspiracy.
Yes, building prisons is expensive. But the current UK government seems to treat it as a physical impossibility, while releasing violent offenders early due to lack of capacity.
UK is the worse for this too.
We have a story in the news currently about a foreign child gang rape leader (yes, those are things in the UK) who raped at least 30 children and was released early after serving just 14 years in prison.
We have major children sexual abuse scandals in this country basically every year too. Politicians never care about that though.
It isn't and never has been about the children.
