Because there are so many true things that any communication is doomed to include only a small number of truths, the truths that are chosen to be told are just as revealing as the lies, if not more so. I would argue that it is yet more revealing a PR firm is hired to amplify specific truths. I'm reading an interesting book about this right now: Truth: How the Many Sides to Every Story Shape Our Reality by Hector Macdonald.

Don't get me wrong, I'm not claiming there is or should be anything illegal about this, but I certainly reserve the right to make judgements of companies that I might work for or do business with based on both the lies and the truths they choose to advocate for.
