What do you think people run on their Hercules mainframe emulators ?

The funniest thing about IBMs mainframe operating systems is the story
of VM. IBM repeatedly tried to kill it off and get customers to use
their 'real' OS, and found it impossible ... especially when their own
internal developers were busily using it to develop that 'real' OS!

Could be one of the factors why IBM dropped open source operating
systems, although the timing could be wrong.
