I think Google is more or less "in the wrong" too, but a less snippy, snarky response would probably do more to convince people of that. "You catch more flies with honey than with vinegar", as they say.

Probably yes.

As a non-native english speaker it is quite difficult to find an enough but not too much snippy/snarky response (had e.g. to lookup these words)).

What are you implying, that when English is not your native tongue, it is easier to be snarky?

English is a second language to me, and I cannot imagine this being true.
