Specifically, his belief is that God forbids networking in TempleOS, not other OS's. (Otherwise he wouldn't maintain a website, upload YouTube videos, or comment on HN.) It may not be a good idea to add networking to TempleOS, since he may take that as an affront to his religion.
So if TempleOS has no license, then it may not be strictly legal to add networking support and then re-release the code. Glancing at the "Downloads" section shows no mention of a license. Of course, no one is going to be able to enforce those protections in Terry's case, but if it's likely to simultaneously offend him and be illegal, is it a good idea?
What a strange situation.
EDIT: TempleOS turns out to be in the public domain.
TempleOS is an x86_64, multi-tasking, multi-cored, public domain, open source, ring-0-only, single-address-map (identity-mapped), non networked, PC operating system for recreational programming.

Under many (if not most) jurisdictions it's not possible to put things in the public domain, and saying you do so without providing an actual license is the same as not doing anything (aka "All Rights Reserved", the restrictive default).
Even in the US, the idea of putting things in the public domain (rather than it falling into the public domain) is a bit iffy and AFAIK has never been tested in court.
Hum, it feels to me there are subtle differences between German and French law. Notably, the right of withdrawal and the respect of the work's integrity go beyond German law.
In French, a piece of work is not "put" in public domain but is said to "fell". It's not something that needs doing, it's something that happen at the right time.
Anyway, I'm probably wrong since I'm not a lawyer :-)
Also, if code has no license, then apparently it's equivalent to having an "All Rights Reserved" notice, preventing any re-use of the code at all, according to http://osswatch.jiscinvolve.org/wp/2013/05/21/unlicensed-cod...
