> The fact that you need different internal descriptors should be a red flag
It can be, and you're zeroing on sense where vague lingo like "enhanced interrogation" replaces plain "torture".
But that's a stretch. Every profession develops their own lingo over time. They're called "term of art" (1)
An example is when one sysadmin asks another to "bounce the box" - these words have specific meanings which are opaque to outsiders, but are brief and precise to insiders.
This "internal lingo" developing is normal, inevitable, even necessary, and not in any way a "red flag".
If the admins of twitter had several different terms instead of calling them all the same thing then ... maybe they just needed to be brief and precise, to distinguish between them, in order to do the job effectively? You're trying to invent a problem where there is none.
