Very true. However, life is shades of gray, never black & white.
Many of the applications that run on my boxes are vendor applications.
Some are vendors that do not even exist any more.
I have a limited staff (2) and resources to manage > 50 production servers.
Given that fact, I only worry about the ones that are taking a major time to run once or take a medium time but run many times.
In short, I kill the large elephants but a lion or two might still be out there.
But if they do not bother anyone, I do not worry about them.
Good luck in your endeavors!
