I understand why the LEGO corporation does it, but it's their problem, not ours, and we don't really need unpaid lego consultants running around lecturing people about the "correct" way to refer to them.
WHAT? DOESN'T EVERYBODY SHOUT WHEN THEY SAY LEGO??
>"Legos" is clearly in common usage
Given that I don't ever hear people using it.
Personally I get faintly annoyed by people saying "legos" the same as I would by people saying "sheeps" instead of sheep when referring to multiple, although I don't think I've ever corrected anyone over it.
I certainly do. The people around you are not a uniform sample of all communities on Earth.
I think americans started calling lego legos because they were already calling eggos eggos. In the uk and europe generally we don't have eggos, so we don't have legos.
I checked the wiki page and thought the contrast between the two approaches is interesting.
Also (child of the 70s) I am certain that I was calling mine Legos before I even knew about Eggo waffles. Third - boy I'm really piling on, sorry - I don't think I've ever referred to multiple Eggo waffles as "Eggos", probably because there's already "waffles" for that.
