It’s been known since before launch that it wouldn’t come with a display port cable. Not sure about the Bluetooth thing. I couldn’t say for sure, but I Imagine it probably says something in the item description and on the box itself.

At the same time, unfortunately it is pretty standard among electronics in general. Photography, synthesizers, music equipment in general, PC parts… When you buy a pc case, you expect the bare minimum to include screws, but they don’t always include things like SATA cables.

However for VR, a simple adapter should definitely be included. I just can see why it wasn’t given the history of electronics.
