Here's what I said on the MVS-OE list. It's quite a different take on
the topic than others have posted. It boils down to "We've been
spoiled by IBM" which, I suspect may prompt an argument.
Here are a couple reasons that seem to be mind-set
differences, and my mind is too set to easily adjust.
Messages:

Now how in heaven's name do I look up those messages?
I happen to know that the last 3 are ok, but what is the
significance of the first one? The colon seems to imply
it may be a header for the following messages, but I have
no way of knowing for sure. And is S_AGV123(837) good or bad?
Or commands:
ping 1.2.3.4 -c 10 -s 10.9.8.7 -t 15 -l 1024
vs.
ping 1.2.3.4 Count 10 SRCIP 10.9.8.7 Timeout 15 Length 1024
Just a matter of familiarity, I guess. But if I understand PING
I can pretty much guess what the parms in the TSO command mean,
even if I've never seen the command before.
Not so, the Unix format.
Having spent the last 36 years working on various IBM operating systems
(mostly flavors of MVS) I am definitely a Unix novice. I get the
very strong impression that developers of Unix applications either
assume there is no such thing as a Unix novice, or that novices are
not welcome.
I'm not at all surprised that MVSers are reluctant to join the Unix
world. It doesn't want us.
