... and typing 'www.fox.com' into a web browser get's you (well, me) a
picture of some alien person with a ray-blaster and some woman who looks
very vaguely familiar (I'm a little behind on popular culture). In other
words, even though it is "incorrect", it is working well enough that people
get to see, er, whatever that alien chappie is.
Perhaps the underlying message is that the DNS works a bit too well?!

Well, that could have:
1: refused to make the change
2: been sad.

There are various policies which prevent #1. I'm all for number 2.

I think that part of the issue is that gTLDs are generally not incentivized
(or allowed) to care about this - perhaps this is the actual problem we
should be solving?
