If you do not use any names can you violate someone’s privacy?

If you said on a billboard, something that happened to you but you did not mention anyone’s name; can the other party in the action on the billboard claim a violation of their privacy? The random person driving down the freeway would not know who was being mention. The people who are friends to either party would know who was being talked about but since they already know them how is privacy broken or secrets leaked?

What if it was the actions of a company or organization and not an individual, is that a game changer? If a person said on a billboard, ”My nation wide coverage would be great if the nation was no larger than the Vatican, and their Droid phones suck”. Even if there were only two cell phone providers that would fit the bill since no business name was mentioned can they fry foul?
