Well it depends.

For example if an application uses Bigtable, then the key + column names often gives a lot of information about what data is stored there, which if somebody had access to some basic application data they might be able to get at somebodies specific data.

However as you might expect there are many safeguards in place, including ensuring every action is fully and securely authenticated so even low level SREs cannot read application data without a paper trail. This story is pretty surprising to me, and if true this guy is an idiot.
