Nintendo and Lego are on the same level when it comes to sue people for trademark violations. There are several cease-and-desist orders against YouTubers for calling no-name bricks legos.
This is how I feel when I hear or see people use the word “maths”, but I simply accept the cultural differences in language.
Though I don’t think throwing an “s” on a word to make it plural, even if technically incorrect, is on the same level as “basgetti”. Adding an “s” to words to make them plural, is generally a good rule, there are just some exceptions, and not that many people are deep enough into Lego to know it’s one of those exceptions.
From my experience they also have quality as a moat. No budget manufacturers seems to be getting the tolerances Lego is getting. There could be producers that are getting there though, but I don't know them.
