IBM has started to wise up to the necessity of what amounts to "hacker culture" in keeping products relevant, desirable to work on, and secure. I'm not sure what it would take to get that kind of openness where a hobbyist could run z/OS. There are a few ingredients to the success of z.. the hardware, the OSes, and the sheer backing and commitment of IBM. I don't think any of those things are orthogonal to opening up the platform a bit now days. In the past, "plug compatibles" where kind of a drag. If production customers used emulation to run workloads that would cause ecosystem issues. Other than that it is just hard product managment and leadership issue
