Recently there was a days long blackout in the middle of winter in Berlin due to a left-extremist attack on power line infrastructure [1]. This was mainly because all those critical infrastructure information is publicly accessible. I can imagine the goal is to prevent such critical information being publicly available in the future.

Also, there was big scandal from then health minister of Germany [2] and the information came out through various media out lets. I can imagine the politicians wants to prevent that happening in the future as well, so the corruption would go undetected (this is just my opinion)
