Open source is a red herring, as you say. Closed binary is the problem.

I need a way to verify that binary I am installing is the same as the binary that has been thoroughly vetted by security researches. In the modern mobile app ecosystem, on a major OS, running a major app, I can't carefully pick and choose which binary version to install. I get whatever the OS company's server pushes to me, and I can't downgrade to a known good version.
