Pedantry is necessary if we are going to talk about computer bugs and flaws in the intended behaviour of systems (AKA the "hacker" part of "hackernews"). I hope we never change.
I know many hackers who can communicate just fine without redirecting conversation to a debate over the meaning of words. Semantics are trivial to clarify. Pedantry honestly has very little to do with building things except when resolving miscommunication.
Besides, words have multiple meanings, and there are many floating signifiers in the world. Correcting diction without an acknowledgment of intent might as well be pissing into the wind.
On a personal level, aimless pedantry is a terrible attribute in people you work with, and these people can be toxic to productivity.
