There is nothing dark happening here, just another SNAFU. It's just the general clusterfuck that is digital certificate management and yet another example how something as stupid as a "licensing issue" creates global outages. This isn't the first expired certificate that will do that it and it won't be the last...
The problem isn't so much the Sony projection system though, but rather a stupid oversight of Deluxe: The fact that the signer certificate of the keys that unlock the content have expired. Although the DCI specifications, which apply to Digital Cinema systems like this, specify that those certificates need to be checked for validity, the specifications are ambiguous on WHEN they need to be checked.
So, other projection system vendors (Barco, Dolby) aren't necessarily affected, because they probably checked the validity of the content regarding those requirements, when it was loaded onto the system and not again during playback. When those movies were loaded onto the system, the expired certificate was still valid. Another vendor that seems to be affected is GDC, they probably interpreted the vague DCI/SMPTE specifications the same way as the folks at Sony...
This all happened, because Hollywood wants their precious content to be protected from the evil pirates, but on a day like this, it feels like the pirates win every time...
