It’s just the right and socially pleasant thing to do, as is graciously responding to the apology and admitting it comes with the vibe coding territory.

The business reason for apologizing would be to placate a customer and show other customers the company wants to improve in this area.

Edit: being downvoted for thinking it’s good to be nice to others shows why we really need people being nice when they don’t have to be! There’s a shortage.
