The most disturbing thing about this saga is that websites that have no physical/legal/business presence in the UK are proactively geoblocking UK-origin IPs. Censorious governments have always been a thing since the beginning of the internet. Websites (especially non-corporate ones like 4chan or R34) preemptively surrendering to a foreign government that has no jurisdiction over them is what's new.
We have seen the same with the GDPR and now also with the UK Internet Safety Act.
