I believe you misunderstood Eisenhower's intent if you believe it applies to a science project like this.

> In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military–industrial complex.

The key there is "unwarranted influence". AR toys are not a tail wagging the dog. It's not the military overstepping the extremely limited boundaries in which it should be operating.

To muddy the waters by bringing it up with every little acquisition the military does harms the wholly justified effort to restrain and constrain the military industrial complex.

United States Gov buys a lot from MS — not just this.
