You're right that HR is never your friend and today's world is so small, but my take: Be cautious with your words while offering genuine, constructive, and non-personal feedback.
It's possible that HR will never do anything--covering for a toxic middle manager--yet expecting to see action from a single exit interview is unrealistic.
SO! While you're not obligated to give any honest feedback, but if you like your coworkers then it's worth a shot.
