What we need
What we need is another blackout day like we had for SOPA. Coordinate a day where google and facebook and as many sites as we can get to show Australians a black page saying "Welcome, Australia. We'd love to show you our page, but we need to be able to do that securely. If this bill gets into law we won't be able to do that, and our solution will be to simply block Australia. Here's Peter Dutton's Office phone number in case you wanted to tell someone what you think of that. Love, The Intarwebs".
I wonder who would back down first. I give it about two hours.
