It leaves the factory missing a part that allows it to function as advertised and intended. That is the definition of a manufacturing defect. It's not a major defect; you can still drive the car just fine and get around it by using the glove box, but it is still a defect. Also, can cars missing the USB module save dash cam video? Normally you use one of the USB C ports to plug in an SSD. If you can't, that's another missing feature.
True, Tesla gets it's share of undeserved negative press, but they don't need to add to it, and when there are reports that are accurate, the negative image they portray indirectly gives credence to the other incorrect reports.
This likely will have very little long term negative impact on Tesla, but it may and for any company to have an issue like this that is completely avoidable is really not acceptable. If I were an investor and I saw missteps like this because of the lack of a functioning marketing department I would not be happy.
