Any content you post on Stack Overflow is licensed (by you) as CC BY-SA [1]. Which is fantastic! Your answer can be freely (with attribution) used elsewhere. Admittedly, the main use has historically been clone websites that just add adverts with no value. But the principle is there. But if anyone has a license to use your content... Then certainly Stack Overflow do! If they want to post an old version of your question/answer that hasn't been overwritten with a message about some cause you care about, important as it may be to you, then they're free to do that.
