@scottjenson I think any service with an implication of privacy should be encrypted, but that encryption needs to be done right. And the UI needs to convey the level of encryption clearly so people don't make incorrect assumptions about the security of their communications.
So I'm okay with the UX coming first, if it's designed with future encrypted messaging in mind.
I get DMs are not the focus of the app, so probably not a big priority, but they are still useful and important to many users.
