1) The simple meaning is that bottled-up feelings may accomplish nothing. Open rebuke might bring a positive result, while hidden love will remain just what it is.
2) A deeper meaning (Metzudoth commentary) based upon the flexible Hebrew preposition, is "An open rebuke is good if it stems from hidden love," even if the receiver of the rebuke is embarrassed, because the rebuker has loving motives.
One of the things that the second meaning (above) alludes to is the vicissitudes that the Jews have been subject to in their 2000 years of exile. The good in these tribulations lies in the fact that they are based on God's love for us (Amos 3:2).
