don't be so mindlessly ethnocentric! They obviously
are not tagging because they didn't notice the "US" in the original post.
They are clearly tagging it because they are sick and tired of Google releasing products and services that are only available in the US.
There is the dubious excuse in some cases such as licencing, for media for instance. But no excuse for things like this. They even have a licensed store that ships merchandise globally (Google-store.com) why not at least release stuff through them?
It's just irritating. But frankly, worst are the many free web services that Google provide only in the US. The ROTW generate over half Google's income to pay for these services, but almost none of it benefits from it. So yes, you might be alright, jack, but this is a legitimate issue for others.
