I think the two of you are displaying my issue with the whole post which is that feedback is highly situational. Trying to distill this subject down to "Don't give your two cents" or "Only give your two cents when you're right" is pretty much impossible. There's so much context missing here.

There's a much longer post to be written on the ways to provide feedback and create a constructive conversation around solutions and seniority is almost never the reason someone is right but experience most often is.
