So regarding hypocrisy, while it's true in certain contexts and under certain conditions, calling out hypocrisy, could constitute a logical fallacy, simply stating that possibility, says very little about how to value it.
Is hypocrisy good or bad? Perhaps the question is ill-framed. Avoiding hypocrisy, can create a powerful resonance between the speaker's aligned actions and words. It may be worth nothing this not a moral value judgement, but speaks to leadership. People on average, appear more willing to follow those with strong and bold congruency, and yet abandon them, when that illusion shatters (aka Lance Armstrong).
That said, my own view is that hypocrisy is generally inefficient, as it appears to increase the noise in the system.* As the proverb goes "talk is cheap" and hence it costs little to put an opinion out there, which is not bad in and of itself, merely that it requires little effort.
Thus with a sea of opinions floating out there, and limited time to process (if your cognition doesn't naturally operate in a frequentist manner), who can you trust?
There does not appear to be a definitive set of answers, however the heuristic of matching words to actions, while not perfect, combined with a test for integrity, has personally proven useful over the years.
