Skype, in its sole discretion, may modify or discontinue or suspend your ability to use any version of the Skype Software, and/or disable any Skype Software you may already have accessed or installed without any notice to you
What this means is that at any point in time, skype reserves the right to hit the self-destruct switch on the software on your computer, and there's not a damn thing you can do about it, because you allowed them to by using it. Furthermore, they reserve the right to change the rules at any time by posting said changes 30 days in advance on their website, so it's your problem to check their website regularly. And best of all, this whole transaction is subject to Luxembourg law, and if you want to sue Skype, presumably you have to do it in Luxembourg.
