What bad things were done to open source roguelikes? Nothing bad really happened, because only good games survive. Trust me, bad variants will be forgotten fast. Like I said and this is just a guess, but the real reason why TB doesn't want to release the source code is that someone will improve ADOM, make it better than he ever could. Now that would really depress you as game designer. If you ask me, I wouldn't release the source code myself, for the same reason.
