Describing or at least providing context is not editorializing. I don't know how this "discouragement" is phrased, but it should instead encourage (if not require) that titles mean something to a general audience (at least as represented by HN's users).

I am routinely down-modded and even banned for merely asking for more-descriptive titles. It's anti-user, anti-community, anti-usefulness, and douchey.

All we needed here was, at least, "Bluesky Social allows domain hijacking" or whatever it's actually doing (which I don't have a grasp of, even after following the cryptic link).

Or even just "This guy is now all of S3 on Bluesky Social." But that wouldn't be as click-baity, would it?
