There's no word in the english language for how tragic this is. As a sister comment mentioned, the cruelty is the point.

It's a long shot, but is there any material way of helping these artists be able to take their art with them again? Making noise at specific people? Organizations that specifically target these broken freedoms?

Artistic freedom in particular is a very near and dear subject to me, and would greatly appreciate pointers here if there's any existing work done here.
