Whether or not they care isn't the issue, they still have that data (I'm assuming it's quite detailed and invasive). Things can happen, data leaks, unauthorized personnel accessing for their own gain etc...
Two wrongs don't make a right and although I'm specifically asking about CoCT taking aerial shots of houses, with Google you can at least report an issue should something of a private nature be exposed. We don't necessarily have that right here, as far as I know. In other words, a private entity is exposed to various laws and regulations, especially a global one, they need to comply or **** hits the fan. But something like this, we lack the power and insight into wtf they're doing.
