I’m thinking he posted about it so that people would know what happened to him if he disappeared. Also, if he did disappear, it would be the only chance to tell of the corruption and evil of Ukraine. It also brought his case into the mainstream, and is likely why Elon is involved. I imagine Hungary was also notified by it and waiting for him.
Sadly, his posts also may have triggered them getting him behind bars again. Without them, he may have made it to Hungary. What a horrible predicament to have a loved one endure.
That’s true, you put it very well, showing his two options. He sounds like an amazing man because he picked the option of danger to himself but getting the word out.
