“Patronizing” seems to be a matter of taste. I’ve never considered it to be patronizing; indeed, that’s often much unlike articles which have their title changed.

As far as simply differing, much of the time there’s a character limit that’s hit. I’ve seen many posts with comment from the poster calling out their edit to the title and the character limit is usually cited.

It would be especially difficult to keep the character limit (I think there are legitimate design reasons for this) while also requiring that the title matches the submission as closely as possible. Who decides what words are omitted without it potentially being any of: patronizing, inaccurate, or misleading?
