well sure. i’m not saying people should be calling them lego bricks. it’s fine to call them just legos or lego.
but i think you missed my point, which was: don’t get all preachy about “you have to call them lego, you can’t say legos because it’s wrong”, when it’s equally as fucking wrong to call them lego. The company tells you to call them lego bricks, so if you’re going to go around telling people that one thing is wrong, you shouldn’t be telling them to instead use something else which is also wrong, because then you’re just being a douchebag.
The equivalent here is if you were to call the markers “sharpie” as a plural, and go around confidently telling other people they’re wrong for saying “sharpies” because “look the company calls them sharpie permanent markers, so the proper plural form is obviously sharpie, just like how it works with dice/die” (which, again, there is no way in which the lego or sharpie situations are similar to the pluralization of die).
