The controller, who is also a journalist, has been threatened by idiots, who seem to think she is in some way responsible for the accident.
Here is my free translation of the sad part of her letter.
"Unfortunately, my journalist colleagues have caused ignorant people, unfamiliar with this occupation and above all ignorant of the procedures, to threaten my physical integrity and personal tranquility, so I have been looking at ways to solve this situation and hope to discuss the matter with the directors of our organisation."
The first part of the letter to her ATC colleagues is thanking them for their support and solidarity, and explaning how she is convinced she did everything humanly possible to save the lives of those on the aircraft.
