The point isn't to change history and remove it from the internets, the point is to not be a dick.

You can't delete things on the internet- content is mirrored, and popular posts like that are quoted, copied, and scraped across the internet. There's no risk of the post disappearing.

However, when they're in a meeting with the head of Match and their team, it'd be pretty dickish to keep the post up. It's rude. Removing it removes friction between the teams, is a nice peace offering, and in the end changes nothing- the post is instantly mirrored.
