Edit: To clarify, from what I can tell no one has ever paid even a cent for VLC, though they may have donated to the VideoLAN project.
And regardless of whether you feel that they had any moral responsibility to fix the vulnerability anyway, it's hard to fault VideoLAN here since that is exactly what they did (unless you believe Secunia's side of the story, of course).
