Not so fast
While you jump up and down about how much Zango stinks, you might wish to remember the law of unintended consequences. CDA? Really? The CDA was designed to help service providers avoid being sued for filtering people it thought, in good faith, should not be posting on their services (remember Compuserv?)
Now - ANY APPLICATION that checks for updates from a server (ie. all of them) can be classified as a "service" under this 9th circuit ruling. So, no security drones, you won't be sued but get ready for all out warfare because the malware guys are going to be able to knock out anything they think, in "good faith" should be filtered and there's nothing you can do about it. If Microsoft doesn't like Mozilla, Mozilla will be filtered and the CDA stops the lawsuit. Google doesn't like Bing, good luck finding Bing - no lawsuit because Google is now a protected CDA service.
Install a piece of freeware on your desktop to clean your registry - BAM! - good luck ever downloading a competing product - they've been "filtered" and because of the CDA (and the fact that the registry cleaner is a "service" because it pings a lousy update server) there are no lawsuits available.
This ruling sucks. Zango should have won despite what you think about Zango or what you think about Kaspersky. Even the judges admit that this is a lousy law written during the stone age and should be updated quickly by the US Congress.
Your shallow take on this not so complex issue gets a FAIL because of your inability to see past good guys and bad guys.
