If you're a UK ISP owner, you're almost certainly a RIPE NCC member, given the UK is within its regional scope. Therefore, you've probably spoken to other RIPE NCC members via mailing lists or meetings at least once. Since I also represent a provider that is a RIPE NCC member, I can object that not everybody shares the same ideology you noted. There are some providers that actually speak in favor of such over-regulation and censorship. Everybody can read and/or participate in the RIPE Discussion List, though, and you will be amazed by some responses from ISPs that speak in favor of such measures.
But the good news is that at least the majority (for now) is against it.
I speak for another RIPE NCC member when I say that that ideology is limited to a very small minority.
Even outside ideology, plain business sense makes ISPs not want to deal with censorship & co. It's work to do that, hence costs money. But there are also ISPs resisting out of ideology and civic duty.
