Come on, why are you defending a misleading marketing tactic. Any American company that announces in English it "launches in 180 countries" tends to imply the G20 is in it.
To say that someone is implying something that's false implies that they are misleading on purpose. And I just don't see that here. Yes, there was a time when one might have assumed that if a product is launched in 180 countries it includes the G20. I guess that's not the case anymore.
I'm sorry it IS misleading on purpose, Google's previous product roll out for 180 countries have included the UE.
Unless they have a statement about the why/how, it's still considered misleading. Hard to prove in court that it's misleading to investors but easy enough to ask around to any consumer on the planet and get the same understanding.
