Unity gamedev: You are wrong about Dependency Injection

Unity in this post refers to the game engine, not the Microsoft framework, nor the DWM.

The title might annoy you, which is exactly what I feel when googled: “unity engine dependency injection”.

Every single link on the 1st page, except the pdf one which I skipped, is either full of straight-up false information about DI, or kind of correct but completely miss the main point.
