I think that is an extremism. It would be a felony, so they could charge you to jailtime, but I don't think that this would be the regular response. I didn't realize you could stream a film over skype, unless your friend plays it on their computer and uses his/her screen as a webcam.
Regardless, there is a record of online activity. If you're streaming from your friend or something, they probably wouldn't know. If one used an organized method of streaming, such as an online collection like youtube, your ISP could have records of your activity and the collections would be shut down, anyway. Unless you use a proxy, which a lot of people do not know how to do.
