If we're talking about the same case, the EU sanctioned him, the man is at least dual citizen, and received Russian funds via his media company in Turkey, then proceeded to say it was all because it was about his coverage of Gaza. All of that is in the EU sanctions page, but "democratic" media coverage focused and pinned it on the Gaza bit.
If you're talking about Thomas Röper (of Anti-Spiegel) and Alina Lipp, well, it's even more clear cut, not sure how are you trying to sell legal action against those as lack of democracy. It's disingenuous in the best case.
Regarding UK, the 12k figure is real but related to all forms of communication, and by large involving threats, domestic violence and the like. Not for "social media posts".
>Tucker Carlson is under the gun for allegedly being a Russian or is it Iranian agent. But the US is a democracy.
Tucker Carlson took the grifter turn and makes money off it, not unlike Alex Jones. He'll behave like anything that can bring him manageable and profitable attention.
