I was thinking... what if my next pet project would be under a license that is NOT an OSI, nor FSF approved floss license?

I need to explore some if these post-opensource licenses.

If anyone has a favourite, please let me know!

Clarification: I am not looking for a FLOSS license that is still FLOSS, "just" not FSF or OSI approved. What I am looking for is very explicitly not FLOSS.

As far as freeness goes, my guide is the Debian Free Software Guidelines. I have my complaints about Debian too, but I still trust them far more than the OSI or the FSF, so their definition is what I use. The license I am looking for would not be considered Free Software according to Debian, because I want to break rule six: No Discrimination Against Fields of Endeavor, and perheps even rule five: No Discrimination Against Persons or Groups.

I'm still looking for something that's free software-ish, in spirit, but not technically that.

So far, I had a brief look at:

The Komorebi License
Various PolyForm licenses
Licenses mentioned by the Organization for Ethical Source

There's a lot I like about Komorebi & PolyForm licenses. There are common goals we share, but neither is an exact match - partly because I'm not exactly sure what I want yet. Not exactly.

This will take a bit of time to figure out. The last time I swapped default licenses (from AGPL-3.0-only to EUPL-1.2), that took a good while too, and the task was much simpler too.

This time it is more complicated. On the other hand, there are projects where I am the sole contributor, where I do not accept changes anyway. I can use something like PolyForm-Strict or Komorebi there today, as an experiment.
