Let's see, what has the US government been up to since they terrified their citizens into acquiescing the establishment of a police state to "protect them from terrorists"? Kidnapping people and imprisoning them in secret prisons. Torture of innocent people. Holding people for many years without trial. Need I go on?
The American security services buy data from commercial vendors. So tell me then, why would I want information about me to be sold to a country like that? Maybe, perhaps even likely, nothing would happen. But why take the risk? I mean, look at all the security theatre we go through to avoid the miniscule individual risk of terrorism. Why should we take the threat posed by the US Homeland Security any less seriously than we do terrorists?
If the American businesses who are complaining about this don't like it, then perhaps they ought to be spending their lobbying efforts (and money) on getting the American PATRIOT Act repealed? I suspect an awful lot of ordinary Americans would be pretty happy about that as well for their own sake.
