One aspect I've not seen mentioned is there may well be things such as comments & labels in the source which haven't aged well. Not only profanities, but they could be littered with labels indicating different attitudes to race, gender, religion, politics etc etc which would be unpalatable now. In the early days with more solo and isolated developers I'd expect there is quite a scope for this to have happened. The company releasing it and also the author could well come in for a hard time. There have been a few high profile instances where a Tweet/BBS post from 10-20 years ago has come back to haunt people. Sometimes it's best playing it safe and keeping it locked away, if it still even exists.
