Germans do happily register every change in their adress to a 	population register (&quot;Melderegister&quot;), which is also required by the law. This data can (and will) be sold for profit by the administration and an opt-out is only for a limited timeframe.<p>Germans don&#x27;t care at all about stuff like this. Instead I bet they would be outraged if a US based company did the exact same thing.
