In addition to the other comments, it should be noted that this happens after the fact. You don't really know what your bugs will do until they turn up, which you can only know after you run the program.

Similarly, they didn't know what their results would be until after they ran the experiment. At that point, they can either: share the results, or hide the results. Hiding the results is the absolute worst thing that any scientist can do. The only time the option not to share the results would be acceptable is when they can be discredited or discounted (and sometimes they should still be shared). Since they couldn't discredit their results (they tried), they took the only responsible option remaining.

Indeed, they didn't just publish the results, they asked others to look for the bug. Like others have said, this is the best possible outcome.
