It's not that weird. There are other cases like it. Jacques Baud is a Swiss guy and was sanctioned by the EU Commission for "spreading Russian propaganda". At the time he was living in Brussels and the EU became a prison that he's not allowed to leave.

The sanctions imposed on December 15 by the European Union against Jacques Baud and eleven other people include the freezing of their assets, a ban on doing business and bans on entering the EU.

“I don’t have the right to return to Switzerland, or even to travel within the EU. I’m essentially being held against my will,” says Jacques Baud.
