The Nintendo Switch has been the best-selling platform in the US for 10 straight months. However, to me it sounds like a conspiracy theory that Sony is behind NPD and Media Create not releasing figures.
But Wii and 360 both outsold PS3 for I don't know how many straight months and we got NPD numbers anyway. If I recall correctly NPD's ninjas started hunting down leakers long before Switch launched during a time where PS4 was the best selling console in the US. I struggle to see what Sony would gain from hiding those numbers.
I agree with this sentiment and I want to add that NPD has been doing shady crap for a long time. Let me remind everyone what an NPD report looked like back in 2008.

Notice the differences? Here are at least 3:
1) Hardware sales numbers. (I.e. the thing we have talking about in this thread.)
2) Software sales numbers. Yes, the NPD actually used to give us software sales number for the top 10 games of the month.
3) Games in top 20 separated by platform. Call of Duty on XBox360 is at #2 and on PS3 it's at #9. This was one of the first things to change though. Notice this chart is full of Nintendo games. At a certain point NPD started combining these numbers for XBox360 and PS3 games together, so that Call of Duty, for example, would move further up the chart. Just this one change made it look like XBox360 and PS3 games were selling better than Nintendo games all of the sudden. (However Pokemon titles are always separated into two entries. Isn't that "weird"?)
My take on this is that there have been shenanigans going on for a while with USA reporting, but I put the blame on the NPD themselves. They are a business and a lot of their customers are AAA Western developers. They want to keep their customers happy, right? So, whenever sales start to look favorable toward a Nintendo platform, then more information starts to disappear. AAA Western devs want the Sony and Microsoft consoles to look good, because that is where their biggest games go. NPD doesn't want to be the bearer of bad news to their customers, so they have to change how the data is reported whenever they have to be the "bearer of bad news".
