In the physical world, we have the right to print and sell books. Anyone trying to stop us would need to go to court. That right is weak in the UK (consider superinjunctions), but at least it exists. However, to set up a website we need the co-operation of a domain name company, an ISP, and often a hosting company, any of which can be pressured to cut us off. In the US, no law explicitly establishes this precarity. Rather, it is embodied in contracts that we have allowed those companies to establish as normal. It is as if we all lived in rented rooms and landlords could evict anyone at a moment’s notice.
States seek to imprison the Anonymous protesters rather than official torturers and murderers. The day when our governments prosecute war criminals and tell us the truth, internet crowd control may be our most pressing remaining problem. I will rejoice if I see that day.
