Surely they can. Who would be locking them out? Another google employee. So the useful questions are which google employees can look up people's locations, and through what process?
Some people need to be able to do that as part of their job. Either directly for some good reason, or indirectly (they are a DB admin). The question is what controls they have to ensure only those people can look such things up and that they don't abuse those rights.
that's completely different. Can an accountant or marketing person look up a persons location vs can any developer vs can any map developer vs specific people with proper access controls
