Actually, having read it carefully, it is interesting that they actually don't claim it was hacked, they claim that the modification was unauthorized. They also don't claim that they removed the access from that mysterious "employee" who modified it. I'm thinking they had some legal reason to technically not lie.
Yes, this just makes it worse. 'People are thinking we are a bunch of clowns, and for the record maximum truthseeking that is a lie, we are amateurs and clowns. Anyway we are now going to post some technically true but not relevant to the incident information, and as you brought up the highly debated subject of white genocide in South Africa we are going to give all our white South African employees giftcards.'
