Sure, Yes Man ending does feels like a bit easy golden ending to acquire if you make your character invested to the game, doing sidequest and stuff. But that's the point of the ending.
@Walpknut Then I refuse that definition. It is the most biased classification that I ever heard. There are lots of cut content that provide more context to the unpolished vanilla game, that only did not make their way due to short development time.
The problem with their reasoning however, is that they seem to just capable accepting Todd Howard lore explaination in stream, but not so much for Josh Sawyer interview.
Josh Sawyer himself has said that cut content is not canon, and a lot of cut content was cut precisely because they didn't want to make it a explicit element.
