Google licence (some of) their map data from various national mapping bodies, e.g. Britain's Ordnance Survey. Google's licences from those mapping authorities don't allow them to use the maps for satnav, so Google have to restrict their licencees.
If you want to complain, then it's national government (cf Guardian's Free Our Data campaign) that you should be complaining to, not Google.
