I think that what happens in lots of activities is that new terms come into being, and it takes a while for everyone to get on board with common terminology. When I first started diving, the apparatus people wear to control buoyancy was called (in my observation, at least) a BC and a BCD in about equal numbers. I think the usage is moving much more to BCD.
I personally use tech, which is, of course, a problem because I teach PADI Tec and have to use that when referring to the course titles. (No, I have no idea why they made that decision.)
I am also the kind of guy who does not fight over issues like this, so if someone writes something to me using a particular spelling, I will usually respond the same way. No sense making an issue out of it.
I ma a friend of Michael Menduno on FaceBook. Perhaps I should ask him.
