To put things into perspective, the plaintiffs lawyers, Waldorf Frommer, are known for shady tactics. They have built an industry of putting immense pressure on private people. They don't shy away from lawsuits because they are cheap for them and menacing for the people. They don't always win, but under the line it is a very profitable business for them; they employ about 60 lawyers.

The public broadcast made documentaries about their cease-and-desist-industry against private people. Even the German Bundestag changed multiple times the law to stop that madness, but it took many years because the christian party opposed effective changes. Now, even though the law has changed on the 13th October 2017, they continue to pressure people into paying.

Some courts are heavily in favour of them, most notably the Amtsgericht München. This makes the situation even worse for people who cannot afford to appeal a judgement even though they are convinced they are not guilty, because the financial risk is too high. I would not be surprised if the judgement in this case gets overthrown in a higher court.

The defendants german lawyers, WILDE BEUGER SOLMECKE, are known for legal defense against Waldorf Frommer. Personally, I don't trust them completely because they offer an all-inclusive legal defense package that is conveniently priced at 2/3 of the value Waldorf Frommer asks for. This industry is a huge employment scheme for lawyers.
