There’s plenty of neo-nazis in the Free Software movement. It’s “Free Software”, not “Free People”

it’s source available, and most of the code is public, but you cannot contribute or fork

it’s not open source

This has a lot of potential to overcome the failures of the last decades of hackerist unadoptable software.
