The spyware that Sony installs on the computers of music fans does not even seem to be correct in terms of copyright law.
This article is a translation of this article I wrote for Webwereld.
It turns out that the rootkit contains pieces of code that are identical to LAME, an open source mp3-encoder, and thereby breach the license.
It just keeps getting worse for Sony. It'll be a long time before I knowingly buy anything from Sony again.
