There's a question asking for an in-universe reason why "Imperial Droids" don't appear in the Star Wars movies outside of Rogue One. The OP asked this because they didn't know what K-2SO's droid type was called outside of "Imperial Droid" and really just meant that specific type of droid (this was clarified by the OP in the comments). However, there are already five answers with 10-20 upvotes along the lines of "actually, there are droids used by the Empire" that nonetheless seem to have completely misunderstood the intent of the question.
I edited the title to clarify, and then another user changed it back, per Best policy when edit to question invalidates the answer, which makes sense to me. Is there anything that can be done to improve the quality of the question/answers, though? It seems like a reasonable question, which other viewers of Rogue One probably wondered about, but now it's apparently been hijacked by a spirit of "ha! I can't believe you don't remember probe droids!"
