They find fault with edgy caller referring to technology used by Irish Computer Society (7)
I believe the answer is:
critics
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe you can see an association between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for critics that I've seen before include "Professionals who make judgments on works of art" , "They analyse works of art" , "They judge works of art" , "We review" , "Professional reviewers of the arts" .)
