Definitely a bad look. While he's been vetted and apparently has real connections, reality is I think he might be falling into the same trap many people do - blindly changing stories/arguments to defend/support ourselves and our choices. We all should know this all too well with console wars. How blindly and quickly people can change their stories and their arguments and contradict themselves all for the sake of defending their purchase or platform company of choice. It's really common and it happens in politics and really, anything that has people passionately defending something.
It's just, the thing is, when you have sources - and hey I have had some sources as well I use once in a blue moon on my YouTube channel, there is such an easy and simple way out of things typically. Such as "that's just what my source said". The problem is, he uses very... matter of fact statements, which should only be made by people who have direct knowledge.
Let's say I heard from someone at Nintendo Treehouse about a Switch Pro. Okay, cool - and if I decide to report ont hat or make a video, it would still come with all the caveats any other rumor/leak would of "hey it's just what I was told, but I don't work there so I can't say it's definitely happening". Unfortunately, most treat their sources, even if real, as gospel.
In this case, he seems to keep saying matter of fact things without adding the distance that should be granted of not being the direct source. So he finds himself in hot water, changing his story and maybe hoping his clout will let it slip through. Like so many others do when defending themselves.
The end result: If he has real sources, than he is just shooting himself in the foot for believability. If he doesn't, he's just exposing himself. Neither looks good for him.
