One of the comments on this that I saw was something to the effect of "It's funny and all to get one over on the CIA but you know that information being uncovered got agents killed and imprisoned?"
And like yeah, that is part of why it is so funny. The CIA has never been up to anything good for its entire existence and I won't shed a single tear for their wet works ghouls or people that collaborate with a fascist intelligence agency. Liberals in universe would literally be pearl clutching over the death of an ISB spy (and this is directly alluded to when Mon is all aghast when Cassian claps her driver even though she knows he is spying on her for the ISB).
