It's specially annoying when people use it to latch on to achievements they had no part in. Like Americans today going "We stopped Hitler" etc.

For this reason I've never understood the emotion "pride" when applied to anything you didn't personally do.

For example pride in getting a bug fixed, or running a personal record lap, makes perfect sense. But "proud to be an American," or "proud of our troops," "proud of some sports team," I just don't get it.

I use it to give credit to peers if I've done something good (and maybe to take/share some blame if I wasn't directly responsible). The one that makes me cringe is people saying us/we when referring to their preferred sportsball team though

Ah, in that sense yeah, I also feel similarly. I thought that the article was written by someone on the discovering team, hence my confusion.
