Terrifying.
Thanks to the (abysmal) technical knowledge of our MPs, any site-blocking bill would have flown straight through as soon as the phrases 'cyber-bullying', 'think of the children' or 'illegal downloads' were mentioned. In that light, I think the ISPs probably chose the least bad option - comply, lie low and hope that they can sit it out until the government forgets about the whole thing.
UPD: I should probably have mentioned that I'm from Russia.
Compare to approaches Russian opposition is taking. They have to know law, often know (much) better than judges which don't follow the law anyway - but at least the opposition reasoning and their logical constructions could be heard. I guess, not anymore - state-controlled media isn't going to provide objective coverage of "criminals" in courts.
Sorry, we have secret, closed courts now, without juries. They were intended for terror cases, but are being used a lot more broadly than most think. A barrister friend who raised concerns about this had his career assassinated-by-media last year, and is now a hate-figure.
I'm afraid it's too late.
Edit: This piece demonstrates quite nicely how this variety of assassination happens - you know, writing things in such a way that they look like direct quotes, when they're not, and getting every paper to carry the same story - http://barristerblogger.com/2013/08/29/criticism-robert-colo...
That is really quite offensive. We have a culture of protest and resistance. What we have at the moment is a paradise of easy living. Despite the depressing lie of what the media will give you with "food banks and poverty" the standard of living for most Britons is really quite good, much better than the 1980s which saw major public political unrest.
People won't take to the streets for internet privacy or other such soft battles you can think of. The political classes will chatter about whatever games they play with each other but people really don't care about such issues.
This is that media control thing that's being spoken about here. Go north, my son, things aren't so rosy outside of London.
People won't take to the streets here, full stop. The British populace have no appetite for it.
Sure, some assertions of slippery slopes are fallacious, but others could not be more real.
And UK has already put everything they need in place - next thing on the list, invade Ireland :-)
