I'm not really sure what people expect. The fundamental problem has been and still remains that the email protocol is not secure. If you send email from a gmail account to a hotmail account, it is sent as plain text readable by anyone with direct access to anyone on any of the networks between the gmail server and hotmail server. End-to-end encryption only works if both the sender and recipient agree to use and implement the same form of encryption. Since there's no standard, an email provider like Google cannot implement it on their own without having to field countless user complaints that "my friend at friend@another.email-provider.com cannot receive encrypted emails." Google cannot fix that - another.email-provider.com has to fix it - but ignorant people will still blame Google for it. So they don't even bother trying.
