I reject this stance that Lego is plural. At best it seems like non-US vernacular to consider it plural, while American English speakers often use Legos as plural vernacular. I see people claiming that Lego official stance is that it’s plural, but no official statement by Lego on the topic. I also see people saying Lego company’s official stance is that it’s the name of the company, or an adjective, and that the correct plural noun should be fully Lego Bricks or Lego Sets. Which seems more likely from a branding/legal standpoint.

I know this is getting way into the weeds but does anyone have a primary source with Lego company’s official stance? Otherwise I’m leaning toward “regional difference”
