Besides, the mortar might be dusty, then someone applies some magic sealant and that might be a problem if you ever want to replaster because the plaster might not stick too well to that seal coat. I suppose if you were so much into the industrial look you could whitewash the bare brick - that'd get rid of any dust and doesn't hurt at all.
Well "ruin" might've been too strong a word, but painting brick can never "help" it. There's no question that paints trap moisture, unless you're using a mineral paint, such as limewash. There are brick buildings over 1000 years old on this earth. I doubt they'd still be here if they'd been painted.
