The German government is more worried about prosecuting a group of elderly conspiracy theorists than defending the country from real threats. While the Reichsbürger movement may have objectionable and fringe views, it's not a crime in itself to hold a political belief. Given the remote possibility of this group ever committing violence, we have every reason to question the motives of the government in making an example of these accused.
The far-right in Germany has expanded in influence, and the threat of violence grows by the day. Armed with a cache of weapons and a poisonous ideology, the Reichsbürger members had everything they needed to commit real-world violence. The group's connections to political parties in the country make matters worse — necessitating immediate action to combat hatred before this movement inflicts real-world damage.
