Uh, Google frequently only released products for the US market, e.g. Google Home, Google Voice, Chromecast, and others were released US only (sometimes for over a year before available outside of the US).
Chromecast is physical product, so it would be limited if they don't want to pay international shipping charges. Google voice gives you country number, so it would be limited. Google home does make sense as it could only work with partners so if they launch in other countries without partner, it could mean bad reputation.
Here it is just a site with nothing related to region.
C'mon, we're not talking about some startup here. Google is a global mega-corp, if they really wanted they could launch every single product globally, no matter if physical or not.
