So where does this 'DNS blocking' nonsense end? Well, since it's trivial to set up, all that will happen is that we will have a "Freedom DNS" layer out there. How do you stop that? I guess you could try and block those IPs. Okay, so you layer it on top of a DHT say. Now what? Either you continue to 'whack a mole', or you make it illegal to look up some numbers on the internet.
That's the end point of this, another crazy 'these bits are special and you're not allowed to see/copy/think about them' law. This can only end with more freedom thrown handcuffed into the cellar while corporate interests are getting blowjobs from eager politicians mubling incoherently about 'the children and the jobs'.
At some point there's going to be a physical reaction to this insanity. Just keep pumping up the pressure.
