Sure, there's no absolute right or wrong on terminology, but it is a sign that they're cut off from the software engineering world, which leads to a whole host of dumb practices, described elsewhere in the comments here. As someone with a mathematics background, whenever I encounter someone in another community using mathematics (like economics or accounting or finance or whatever) using mathematical terminology that seems silly to me, it's a bad sign.
