I find that happens to me too (getting annoyed), but it's a good reminder to introspect when it happens. Clearly, there's nothing objectively wrong with actually using these words in their new meanings-- they're completely serviceable in their new usages, and clear too. There's some degree to which all people get annoyed with language changing and feel a conservative impulse to put a stop to it, but the annoyance with office jargon in particular seems to go beyond that. The source of our annoyance is thus revealed to be something else. I have a feeling it comes back to, like so many things, status games. Someone using new terminology that was just invented is (probably incidentally) asserting some kind of status one-upsmanship over you, demonstrating in passing they are more familiar with cultural norms. I wonder if my annoyance is actually stemming from insecurity that the other person is exactly right-- I am falling behind in the invisible status games. I can either accept my loss, try to adapt to it by using it myself, or remind myself of how little I really care about these status games.
