When the UK introduced Cleanfeed to block child porn, it was supposed to only be used for that. But when cases came up in court, ISPs could not deny that they had the capability to block individual websites, so it got repurposed to block things like TPB - which I think is wrong[1]. The fact that Western countries also misuse censorship is no excuse. All I expect that will be required is a compliant court, and further censorship may be applied once the infrastructure is in place.

[1] More widespread use also works against its original motivation, because it encourages people to work around the blocks with VPNs, proxies, etc. But that's generally restricted to very motivated and half-ways technically adept people.
