How is it overkill? It's really simple.
Overkill would be doing something aggressively like doing online checks every 24 hours.
This is passive, and will be broken if it hasn't been already so you can back up your files.
This is overkill in the sense that they are taking needless steps to hinder out experience. If there was an issue with the Wii then this would make sense. Since no hacker was able to do anything to decrypt Wii data I fail to see the reasoning behind crippling our experience as users. It's completely unwarranted.
