You underestimate how the US Military makes purchasing decisions...
Let me provide the real facts, instead of your baseless speculations:
Microsoft and Magic Leap were competing on a Army contract. Microsoft won. The contract is $480 million for 100k units. That's $4800 per unit. 4 figures, not 5. The Hololens 1 costed $5000/unit COTS.
Magic Leap's cost proposal couldn't have been far off.
That's why the military ends up buying hammers for $1000 when you could pick up a higher quality one for $10 from your local hardware store.
You are showing your ignorance again: the DoD doesn't make decisions like these based on monetary value alone. Technical merit was likely the deciding factor.
