I can't help but think of how the original Deus Ex existed in a world where crackpot conspiracy theories like this were just the reality. And this sounds like it would make a great setting itself as some agent works their way through a conspiracy, going on a small world tour of levels in various major powers of the world before finally ending in a boss battle in some hidden hi-tech but occultish basement of the Vatican where we find the Anti-Christ is preparing to unleash whatever high-tech equivalent is for the Mark of the Beast, and it's our final big job to take him down to stall his coming to power for the next millenia or some nonsense.
Sorry if you take your theories seriously, I just can't. But I'd bet they'd make a cool story.
While it's cool the major online retailers have delisted the items, somewhere out there, the group that is the actual third party shop that makes the items is still out there. These major online retailers are just distributors. It's possible the producers may just give up and pack up, but they also may just seek other, less seen avenues of sale through websites that aren't so pulicly at large.
