Really? I honestly just don't believe this... if I were to believe this, I think I'd have to conclude the world is just too broken to bother rescuing.
What did I miss? What's the best answer you've ever heard? How do you evaluate 3rd party dependencies?
Of course there can be libraries that are more or less "finished", so the last commit/frequency of commits isn't on its own a deciding factor, but in proper context/holistically it is definitely an important metric!
