You're so close to what I am currently building that I feel like I have to chime in. I left Apple's security team a few months ago to go solo and build an app that is similar to Facebook/Instagram and Snapchat in terms of functionality and UX but uses the Olm protocol (similar to Signal) to protect all content. So, fear not - something is being done, and I'm sure I'm not the only one working in this problem space. I think it's ripe for innovation, counter to popular belief; the trick is to do it in a way that doesn't require a PhD in computers to operate the damn thing, as was the issue with previous attempts.
