On a slightly broader topic.
After more than ten years teaching punters how to fly, including aerobatics, I learned that snatching at the yoke to prevent an over speed condition was a bad idea. Even if the PF was someone I didn't fully trust (student, FO, whoever.)
My current employer asks us to descend at Vmo-10. Occasionally, we get close to over speed. Anecdotally, the control column gets pulled if it looks really close.
I think an over speed buzzer, with paperwork, is preferable to snatching at the yoke at Vmo.
Thoughts?
