MMIX is created by Prof. Knuth purely for expressing his algorithms. Back then C++ and Java were the latest, hottest sh... (and would soon be outdated themselves). Prof. Knuth didn't like C++ and general programming language fashion. So he invented MMIX. It was never meant to be implemented in real HW.
I don't know whst's wrong with the other CPU architectures you listed. I especially wonder why Sparc wasn't used more.
I don't know of an industry company who builds truely libre hardware. Only half-libre if you are willing to call it so.
Which region are you willing to work in?
I don't think you need a particular order.
Windows -> GNU/Linux
KDE/Gnome -> JWM
TV -> Reading books
Twitter -> Fediverse
Coke/Cola -> Tea/infusion
Amazon -> Local bookshop

But how does plant-based diet reduce waste (as the diagram seems to imply)?

"100% have ignored" Yeah sure, then you don't read newspapers. It is not ignored.
As @sexy_peach@feddit.de said, there is "Last Generation" here in Germany, too. And as you said about Italy, here they are doing more harm than good for climate protection. People who are already convinced that we need urgent climate action like the last generation. But they don't need to be convinced because they already are. And the people who are not fully convinced, they get very angry about the climate movement. In Berlin an ambulance on duty was hindered by the "Klimakleber" (climate gluers) who glue their hand to the street.
Dell and Ikea have already used it. :)
It costs more than plastics. So the politics are on duty here.

I've read about producing packaging and items from funghi (mycels). Maybe that is an alternative?
I just stumbled over this project:
