I assume you mean USS and not Linux on Z.
I am not speaking out of school to say that Wells Fargo is a HUGE user of Linux on Z.
Marcy Cortes has a SHARE talk "Penguins on the Stagecoach."
Any C or C++ program -- assuming the IBM C/C++ compilers -- is using USS (I
would say USS services but that would be redundant).
So I guess all of the customers for my CorreLog -- now BMC -- security product are
"using UNIX."
I don' t understand this; IMHO no correlation between IBM C/C++ and USS -
I wrote lots of C programs (and some C++) in the 1995 to 2019 timeframe
for two different
large customers using z/OS, that were targetted to the classical z/OS
environment without USS,
doing classical z/OS work with DB2 and datasets, interfacing with PL/1
and ASSEMBLER
programs, which did the same (the PL/1 programs interfacing to CICS at
one place and
to IMS/DC at the other place).
At one of the two sites, we experimented with USS, because it was a
requirement for rDz,
but we had to cancel it for some reasons (too long a story to be told
here).
To enable all users to use USS segments for rDz was a performance
nightmare;
the homegrown software development and deployment tools we had (and
which we kept)
were much better in this respect (also located in the classical z/OS
environment,
based on DB2, written in PL/1 and REXX, using ISPF services).
