Gmail's Encryption Warning Spurs 25% Increase In Encrypted Inbound Emails (theverge.com)
An anonymous reader quotes a report from The Verge: Google's efforts to keep users safe might be forcing other email providers to make better security decisions. In February, the company started flagging unencrypted emails, allowing Gmail users to know whether they're sending emails to, or receiving emails from, providers that don't support TLS encryption. Since then, the amount of inbound mail sent over an encrypted connection to Gmail users has increased by 25 percent, Google explained in a blog post released today. The majority of the uptick likely comes from providers updating their clients so they can avoid getting flagged by Google, the company said in a comment to The Verge. Without in-transit encryption, which Google provides by default, emails could potentially be read by attackers because their body and data are sent in plain text.
Google is also going to send Gmail users a full-page warning notice if they click on a potentially malicious link. In addition, they are going to increase warnings about state-sponsored attackers with a full-page alert about how to secure accounts through two-factor authentication and the use of a security key.
In some ways I think of this push by Google to encrypt mail as being like that thing they do in the Israeli prisons, where they have a dummy microphone in the cell that's easily discoverable and avoidable and then they hide the real mics where people go to avoid the dummy one - and pick up all the juicy intel, undetected.
This form of encryption provides the illusion of security; it's like: 'go back to sleep, everything's fine, your government can't snoop on you with it's giant, multi-tentacled panopticon'. All the while, the NSA and GCHQ are rather happy and completely undeterred.
I can't decide who Google is trying to help with this.

You're overthinking this. Google is trying to do exactly what it says it's trying to do: Make Gmail more secure for Gmail users. After investing a lot in making its own servers use encryption for every communication, inside and outside, it really bugs Google engineers that they then have to send plaintext to other mail servers whose administrators don't care enough about security to install SSMTP. Then someone realized that Google has an avenue to pressure other mail providers to step up and that Google can highlight the effort it's put into security at the same time. Win/win: Google makes the world better and looks good doing it.
Why are you looking for some deeper reasons, when the obvious and plainly-stated ones perfectly explain the move?
