I don't think you are crazy at all. The concept of professionalism is about doing things a certain way to indicate to others that you are, of course, a professional. Writing technical documents in the 3rd person is a basic part of what I would consider professionalism in the broader engineering field.

In the software field you get a large portion of people that don't buy into the concept of professionalism. For various reasons - chiefly the hacker culture and the easy of contributing to the "field" means the gauntlet one runs to become a "professional" isn't inherently a given.

As a whole this is a good thing but it does mean if you operate as a "professional" maybe sometimes you have to realize that something doesn't exactly gel with your ethos (case in point). It doesn't mean it is bad; just maybe not for you and yours.
