Her husband is a pro-palestine journalist and she gets her bank accounts frozen because of it what else would you call it?
Apparently the husband tried to (perhaps unwittingly) circumvent the sanctions placed on him through the accounts of his wife. That will get your accounts frozen alright.
I also don't quite buy the whole narrative that he was sanctioned strictly for being pro-Palestine. There's loads of journalists telling the Palestinian side of things, hell even a lot of state media is pretty critical of Israel these days.
I've seen the "evidence pack" that Dogru published (even though we have no idea if that's a complete story). There's definitely some stuff in there that I'd classify as pro-Kremlin falsehoods.
There's also definitely some dishonesty going on from his side: he publicly claims he has no money left and can't withdraw anything from his accounts (or his wife's). But that's simply not true, as he and his wife are both allowed to withdraw enough money to cover basic needs (not even to mention the social safety nets that Germany has, there's no reason for his kids to go hungry).
He's also stated he believes the invasion of Ukraine to be an illegal act by Russia, yet simultaneously promotes the viewpoint that NATO started a proxy war in Ukraine. There's also some very precise wording going on, e.g. stating he's not involved with Red anymore after Russia invaded Ukraine, but Red was controlled by AFA Medya, which he was still very much involved with. That same Red was also taking on employees who were also involved with RT.
I think there's some very good reasons that unions and NGOs, which historically have taken on loads of cases of journalists being unfairly censored, aren't touching this guy with a 10ft pole. The appeals process here is imo too nebulous, but regardless I doubt that he'd actually win the appeal.
