It kind of makes sense. First I’ve ever heard about Ubuntu Christian Edition as well, but it seems to mostly be set up with filtering in mind, with the DNS tools and such. Add in productivity software aimed at preaching I guess, and you have a “safe” OS for kids and the laptop hooked up to the projector at a church.
Ubuntu was the distribution that had me switch from dual-booting with Windows as default to dual-booting with Linux as default.
I also remember ordering an actual Ubuntu disc, with the extra donation to fund the mailing for free program.
Now years later after lots of distro-hopping I just run Ubuntu LTS, and stay on the very boring LTS branch.
