Americans do generally call them legos. The company hates it.

They are Legos, as in "go clean up your legos"

They are not actually Legos. I think most English-speaking countries know this. "Go clean up your Lego", "get the Lego out", "made out of Lego", "playing with Lego".

In terms of Lego vs Legos I think they hate both.
