As the letter notes, Oracle has never actually taken any kind of action to keep people from using the name. They don't even make performative reminders. They know their claim on the mark is weak and they aren't going to waste a lot of lawyer time on it. But it's Oracle, so they won't willingly give up anything that might be worth more than a dime. This is just to note their continued non-action when the USPTO is asked to nullify the mark.
