So some stupid website that has bad takes (not NWR) has reported a rumor that Nintendo is scaling back Switch 2 production in lieu of poor NA sales
The source of that rumor is Takashi Mochizuki from Bloomberg who has a long history of posting inaccurate information about Nintendo. So yeah, there's no credibility in said rumor.
Of course even if the article was accurate, it's saying Nintendo will only produce 4 million Switch 2 for the first Quarter of this year instead of 6 million. That would still be almost record breaking for a Nintendo system this early in its life. The Switch 1 in comparison only sold 1.8 million in Q1 of 2018.
Nintendo's own forecast for the system is 19 million by the end of March, and they were already over 17 by the end of December. Even if they over shipped at the end of last year, we have reports from around the world Pokepedia's success has been selling out hardware everywhere, so not only will they easily reach 19 million, there's a good chance we could be looking at 20-21 million by the end of March. If that happens the system will have surpassed the Gamecube's lifetime total by the end of April. Even if the rumors are true and Nintendo has to cut shipments by 30% of what they planned, that would still put the system on track to have a user base that's bigger then then the N64's lifetime total by the end of this year.
At this point articles and YouTubers that try to doom Nintendo should be treated as comedy. Even in the worst case scenario's, the Switch 2 is on track to be in the upper half of Nintendo's best selling systems.
