But then it talks about distributing binaries. Cry my a river; most FOSS can and should be distributed primarily in source form, in a git repo hosted on a site like github. FOSS software can be released via distributions that can supply controlled, and accountable, and digitally signed binary packages to end users who aren't skilled enough to build from source. This includes Debian, SuSE, Google Play Store, Amazon App Store, Microsoft store, etc.
Training users to download binaries from random web sites? That's a security disaster, and it's a Good Thing that web browsers discourage such reckless behavior.
