The issue isn't changing language, it's quickly changing language

Lingo is used by groups the world over to communicate about complex topics quickly. A side effect of this is that use of lingo excludes those who aren't familiar with the terms. In most settings (like workplaces) this is a necessary evil and newcomers quickly catch on and the language is not a barrier to them being a part of the group while everyone communicates efficiently.

What's going on here is lingo being used because of the side effects, not in spite of them. Lingo is rapidly created and viciously enforced to tighten group bonds and identity based on ideology by using language to distance the group from outsiders.
