I've been all over the USA, continental Europe, and Japan, and there have always been water fountains. Granted, I've never been to one of the "don't drink the tap water" countries.
I just had this experience at CDG, at the AA gate. I really don't know why people seem to think this is a made up problem. You may have found drinkable water at your gate, but airports are big, and your experience is not universal.
