Even the history video says similar messages...
This is already included in the game, in the game menu down on the bottom. It's not exactly the same one, but there's a similar one.
I have other ideas, like cheating. To me, the whole story revolves around 3 people, and three people only. Sparda, Mundus, and Eva. Why did Mundus set out to kill Sparda and his family, nobody really knows this, or how Sparda died. Who is Trish, and what was her previous context?
I wouldn't have had my own opinions or conclusions if I hadn't gone to where Eva hides her son, or how Trish seems to know too much, and seems to understand what's going on...
There is so many questions that aren't really answered. Trish is one of them.
