Because you know... Since there is no 100% privacy and safety, there is just none. So why even bother?
The location of your server or whether third parties have access to that server one way or another should not be part of your security concept.
My point is that if you have end-to-end encryption and don't store or share unencrypted data in the first place, it doesn't matter where your server is.
There is no particular country in the world where you can place your Tor relay or your storage server and be safe against being spied on.
To use the obligatory car allegory since it's Germany we're talking about: an unlocked car with the keys in the ignition isn't any safer against theft if you park it next to a police station. On the other hand you can park a locked car with a live pitbull inside (in the shade!) pretty much anywhere in town and the risk of theft will be equally low.
