One of the big reasons not to share tools that would otherwise increase productivity in a corporate settings, is that people are petty a*holes. They will fall into at least three big negative buckets.

1. Those who will see it as a personal insult if you write something useful and you will then have a target on your back as they work to block you and hurt your career so you never show them up again.

2. Those who could care less about improving productivity and in fact would rather that everything is tedious, error-prone, and time-consuming so that at least it's mindless for them to go about their day.

3. Those who see everything they don't understand through a lens of fear and hatred. They will not understand your tool OR why it is helpful, and will instead see it as an alien invasion or viral infestation in their workspace, and will work concertedly to resist it.
