Dear US citizens - if you allow SOPA to pass, your country will be cut off from the rest of the internet as fast as we can do it. No ifs, ands, buts - you lose.
The internet routes around errors and broken segments as a matter of course - and it treats censorship as an error condition.
I've already moved my business and that of my customers away from US hosting companies due to insane tax laws. I've already registered .CA equivalents of all the .COM and .NET domains I have. I'm prepared to dump you - are you prepared to be dumped?
