This is a pretty common comment. Unfortunately, explaining the background details turns any quantum computing post into an "intro to quantum computing" post.

My current compromise is to just slip in links to the video series Quantum Computing for the Determined [1] and/or a good textbook with a free version available [2], so people at least have the opportunity to get a toe-hold (if they want).
