As someone who doesn't jive with those politics, but I have to think though that they missed a real opportunity to just share the source. That'd be "the truth", that'd prove that social media companies aren't just hard coded to be echo chambers by some kind of evil political robot, but yet the dark patterns are hidden in code that isn't nearly so obvious. Plus it would show they weren't trying to do anything evil with the results? I don't imagine they will be making money with the tech anyway, it would probably end up being advertising?
