[Full disclosure: I work at Google, though the opinions stated below are
mine alone.]

Aurora compromised at least 20 other companies, failed at its assumed
objective of seeing user data, and Google was the only organization to
notice, let alone have the guts to expose the attack [0].  And you're going
to hold that against them?

If you're the target of a state-sponsored attacker, Google is by far the
best place to host your mail.  Good luck finding another provider that
enables SSL by default [1], offers 2-factor authentication [2], warns you
when you're being targeted by state-sponsored attackers [3], and actually
fights overly-broad subpoenas from governments [4].

While I'm writing, I'll also point out that the Diginotar hack which came
up in this discussion as an example of why CAs can't be trusted was
discovered due to a feature of Google's Chrome browser when a cert was
being used to spy on users in Iran [5].  Note that it also provides a good
example of the difficulty of getting away with such attacks.
