this is simply not true. They have no technical means to do such a thing.
And no servers to manage the bandwith.
msn can also not steal your webcam input.
Google cannot do that, unless you install a program from them wich does steal your webcam feed, or unless they have some help from microsoft. A browser is technically not able to do such a thing, without help from flash or whatnot, and then only when the browser is running.
Their servers park may be one of the biggest on the world, but they are not by far capable of handling, storing and reviewing web cam data from everyone. The amount of processing power it takes to read webcams and send adds based on them will not be doable in the next 20 years or so, and even then the costs don't outweigh the rewards.
Msn's server also cannot handle the webcam traffic from all the msners. So on what basis would they select traffic. Also, the program is scrutinized by many security specialist, and they would notice us of such behavior. When doing a webcam talk, there is a direct link between your computer and the person you are camming with, so there is nobody listening in on you. The msn servers have nothing to do with the webcam or audio conversation. it is a direct point to point connection between you and your friend. It does not or never will pas trough the servers of microsoft !
If they did take your webcam feed trough their server, their servers would crash under all those webcamming teens. They are not capapble of doing it any other way.
And really, why would google or microsoft want to see what you are doing behind your computer. I am sure it is nothing they could use, and is utterly boring. Nobody wants to see someone staring at a screen, really, if the cia wants to see my typing this message, they can do so. All they would be seeing is my face and my blank blue wall behind me (IMG:

And i am not just making this up, i have a diploma in I.T. that says i know what i am talking about. (IMG:

So relax, and don't be so paranoid. (IMG:

and they certainly cannot force such a program upon you. If you choose to use gmail or any of their services, you do so free of choise.
Also, such a function needs a program installed on your hard drive to work, wich you choose to install yourself.
