> I'm pretty sure it's not legally possible

Legality wasn't really an issue for authorities in Germany before, even if it contradicted our basic law. Of course it was for national security. It is my goto excuse too if I break any laws.

There is a lot of room between paranoia and being extremely naive in context of state powers.

> Secondly I just don't say anything in my home that's super secret

Then why would the state need capabilities to get this not super secret data?

I honestly expected more from Germany in this regard, especially with the experience of the past.
