I am utterly disgusted with companies that do this, and the problem is that they think they can get away with more and more. A mouse that can only be configured if you have Internet access ? They specifically state they can collect personally identifiable information, and even say "Razer shall not share personally identifiable information with other parties, except as described in the policy below." And since the policy can change, what if to log into the service at a later time you need to agree to the new terms ? Things have gotten beyond ridicule and any customer complacency on this matter should be fought strongly. This is not acceptable at all!
Microsoft is doing the same thing with Windows 8, if you want to buy and use apps from the store, you have to switch from a local account to a Microsoft account, which means the whole OS and not only the store / modern environment is now being used with the Microsoft account, how's that for privacy ? The Smart Screen filter (which is now an OS feature) also comes turned on by default and sends a request to Microsoft to check if each and every one of your downloads is safe. Instead of downloading signature files to check against and preserve your privacy, just like Anti-virus and Internet Security Packages do, it sends a request to Microsoft each time you download something (Microsoft will have data on when you download stuff), with your IP address, the name of the file and some additional information to correctly identify the file besides its name. Yes, you can turn this feature off, and you can use a local account, but thus lose a part of Windows 8's protection and forfeit buying and using apps from the store, so you can see the trend, it's like companies are (some more slowly than others) trying to see how far they can go in harvesting data and habits from consumers.
Also, remember the Cisco routers' firmware from a few months ago ? Same idea.
If people don't come together to fight this, it's only going to get worse and companies will think they can get away with everything.
