I've been hesitant to use Google for services like this after hearing about incidents where Google disabled everything associated with a Google account after detecting some violation of their ToS. I'd hate to lose my domain name because I, say, used the Maps API in some way that Google didn't appreciate. Google needs to be better at siloing their products before I'd consider using them for something that mission critical.
And often it's not a violation, it's an alleged, unspecified, un-counterable data point hidden in Google's cloud with no way for the user to determine what it might have been.
