Sony is learning that stealth spyware is more trouble than its worth:

"California has filed a class-action lawsuit against Sony and a second one may be filed today in New York. The lawsuit was filed Nov. 1 in Superior Court for the County of Los Angeles by Vernon, CA. It asks the court to prevent Sony from selling additional CDs protected by the anti-piracy software, and seeks monetary damages for California consumers who purchased them. The suit alleges that Sony's software violates at least three California statutes, including the "Consumer Legal Remedies Act," which governs unfair and/or deceptive trade acts; and the "Consumer Protection against Computer Spyware Act," which prohibits -- among other things -- software that takes control over the user's computer or misrepresents the user's ability or right to uninstall the program. The suit also alleges that Sony's actions violate the California Unfair Competition law, which allows public prosecutors and private citizens to file lawsuits to protect businesses and consumers from unfair business practices.

I'd guess that somewhere at Sony, a few lawyers are having a meeting with management, and the question that's getting asked is something like: "Explain to me again how the benefits of this DRM are higher than the costs?"
