I am totally disgusted with Sony after reading a report by Techdirt:
This time, it's more about Sony BMG's other copy protection system, MediaMax, from SunnComm. As you may recall, Sony has only recalled CDs using the XCP copy protection technology from First4Internet. Once again, we have Alex Halderman to thank for bringing this to light. Halderman noted that MediaMax has many spyware like qualities and also discovered the security hole in SunnComm's uninstaller. However, the latest finding is perhaps more problematic. The way MediaMax works is, if you have autorun enabled on your Windows PC and insert a MediaMax-enabled CD, it pops up an end user license agreement (EULA), not really telling you what it's doing. If you realize that you don't want this installed on your computer and hit "no," it's already installed some amount of code that isn't easily removed. However, the latest finding is that inserting another (or the same) CD with MediaMax on it (even if you hit no to the EULA again) will install even more code that will run on your machine even though you specifically told it not to.
This makes it really easy for me to only buy music from iTunes.
