Most people will get a chuckle, but I suspect laymen and even Christian zealots will throw a fit.
Like when a normal person gets an error on their screen and it prints “process closed: child killed by parent”. It will probably raise an eyebrow at the very least, lol.
No doubt.
I was once, back at university so two and a half decades ago, helping someone with accessing stuff on a Unix server (he was not much computer literate at all). He was ahem rather enthusiastically Christian, and unsettled by seeing 666, thinking we'd set it up and were having a jab at him (which, in fairness to his paranoia, some of us might have done).
Those files were on a shared resource so shouldn't have been world writable, or even group writable for that matter, so we did report it (the directory wasn't writeable to me, so I couldn't fix it for them), but not because of the concerns our devout compatriot had!

How many laymen are doing port scans, but also don't know to Google "port 666 doom" when they have a question?
I suspect the number is pretty small. Small enough to not really be a concern.
Just my .02c :^)
Edit: casing

Doesn't "with prejudice" mean no appeal?
> SCO filed an appeal later that month.
Is the end of the timeline... and that was 2016.
Today it still makes abundant sense for more generic concepts like where you do HTTP or SSH but to register them to specific companies is amusing and nostalgic.

Unfortunately, I showed some software in a sprint demo once, using 666 as an arbitrary port. I was very clear that this port can be anything, because the software was made to be configurable by the user, and of course the project manager wrote it down and put it in the "official" and released documentation that the customer must use port 666. facepalm.

# Kit Sturgeon <Kit@remotecontrolsextoys.com>Off-topic: It is nice to see my name amongst the register ports.
And how many of the listed email addresses still work.
Concretely your Linux systems probably have a file named /etc/services which maps the string "doom" to port number 666, much as it maps "ssh" to 22 or "http" to 80.
