That's not accurate. The vast and overwhelming majority of all the good things we have now is not the result of open-source or self-powered or free. It is likely the case that for it to be a true success, it needs to be the opposite of free. Just like nearly every other cool thing that exists. You know, like rocket ships.
It seems like you want to solve a political/social problem, with a machine. You'll find out what the inventors of all other machines found out. They will be used for good, they will be used for evil, and the human politics matter much more than the tool.
It doesn't need to be. And it won't be at first, but hopefully it can propagate in such a way that it can be. Also rocket ships is a straw man because they couldn't (and currently can't) be free.
> They will be used for good, they will be used for evil
I agree with you here, so education and peaceful culture will be key. Also a rapidly propagating cheap/free Machine so that it can start delivering the needs of those who might otherwise be drawn into malign ideologies based on inequality.
