Because if they appear to be a normal company but call themselves a non-profit, I want to know what that actually means to them.

Being a non-profit is generally a reason for community goodwill towards a company. Therefore being a nonprofit is attractive both to companies doing good, and charlatans seeking to capitalize on that goodwill.

If you call yourself a nonprofit but don't talk anywhere about what that means to you and why, then you look like that second option.
