If it wasn't obvious that the Debian box is a parody, here's what the ~~Japanese~~ Chinese text along the top reads on each box:

Please read the instructions carefully and use it under the guidance of a physician. It is strictly prohibited to be used in food and feed processing.

Please read the installation instructions carefully and use it under the guidance of the administrator. It is strictly prohibited to use for server installation.

so yes, the title is correct-- this is not a coincidence, the Debian box was made explicitly for this joke

edit: thanks for the correction folks, honestly thought it looked more like Japanese than Chinese at first glance and I am obviously not an expert in either. Appreciate the call-out, very deserved.
