To be accurate. As fun as flying is, there is a need to be accurate. So probably why so many pilots prefer to use the correct term. Also, you spent a lot of time, sweat and tears to get that "certificate" so get it right!
I was in in various "technology" areas for years. So I'm one of those people that like the correct words used as you can spend hours running around chasing the wrong issue based on what you were originally told was the problem, not what had the issue was they were experiencing. My staff would get so ****ed when they'd come in needing me to come look at a major issue and my first words were "is it plugged in?" A large percentage of the time it was not an equipment issue it was a cable or yes, a connector that was not firmly seated.
