It’s an internal product/feature promotion. It’s uncool to title the post and word the complaint (thereby attracting enough rage-votes to get onto the front page) by making the impression that they’re still running pre-roll video ads before the videos you watch. The issue you’re complaining about is a relatively very minor inconvenience, and they would reasonably argue it’s helpful to make users aware of new features.
