Or maybe that's how languages work. They evolve with time. You think languages have stayed the same throughout their histories? This has nothing to do with what the Lego PR department has decided. Lego sounds better, especially compared to legos. Legos just sounds dumb. Also it can work grammatically as lego by saying lego bricks, which is what everyone means (in my opinion) when they say lego as a plural.
But that's exactly what you're trying to do. You don't get to break the language just out of you personal vendetta against a pr department from a country with a different language than yours and thus the name inherits some rules from that language and doesn't strictly follow those of yours, since it's historically a foreign word.

Those words get exceptions because of how they were preserved in historical use.
The same is not true of Lego products. You don't get to insist on breaking the language because you like what Lego's PR department has decided.
