unity is now a spyware program please stop using this engine https://www.gamedeveloper.com/business/unity-signs-multi-million-dollar-contract-to-help-u-s-government-with-defense
The article you linked mention nowhere that this contract make of Unity a spyware. I wouldn't be surprised if Unity was used in the army for many years (like likely is Rust, C++ and Python)
(althought I don't really trust Unity to begin with, be it before or after this contract)
