Intimidatiom
Tinfoil Time - this article is a bit paranoid, but I just had to write it for the links :)
How would you go about muting a few irritatingly loud critics or opponents? What if you where the government, or had contacts in the government? I'd start by seizing their computers, just deprive them of their communication channel. But what if the critics where too many to stop them all? Well, I'd get other people to do my bidding. I'd intimidate people so that they'd keep the critics in check, to keep their own backs free. I'd size not just the opponents computers, but make sure to cause a lot of collateral damage, so that no one would want to be anywhere near those people, or people with their views ever again.
What I'm getting at is a pattern. The same thing happened when the swedish police, indirectly on orders from the US and the MPAA, busted the The Pirate Bay, taking all of PRQs server in one big sweep, TPB servers or not. This is the new world order; you make sure you're not hosted at the same location as some pirates, or your servers might be at risk. You make sure you don't host any pirates, or you might not get any customers at all.
And if you're going to criticise the current laws, the government, or a larger company, make sure you do it anonymously or you might loose your job. And just having an anonymous online account won't work any longer.
Ok, now you can take of your tinfoil hat again. And host a few pirates on your home server, or just open your WIFI to anyone, since you've got nothing to hide, you've got nothing to fear...
