I am not sure that should be hidden on 'quiet'. This is quite important information for some users, and might be treated as lack of transparency from our side if implemented. Maybe we should consider adding manual config option to turn this message off?

EDIT I am talking about usage analytics

I think if someone specifies a --quiet option explicitly then they understand what are they doing already and are probably running dvc init from a script or something.
