It looks like the Raspberry PI version is gone, too. When I first got my M1 Mac I had issues installing QM and looked at R-PI as an alternative -- easy to travel with and I generally don't need a lot of horsepower. However, they fixed whatever was wrong with the installer issue and I've been running fine on my M1.
It isn't clear to me if they will still generate licenses (i.e. my annual developer's ) but even if they will now they certainly will stop at some point :( I was looking at an M2 laptop...
I guess the options are hope the windows version will run under Crossover/Wine or run a Linux virtual on my Mac.
It was a good run.
