Any product fabrication is so much more than the actual product. For a weapon you need steel, machinery, oil etc. Technically the petrol station near the factory also profits from the weapon factory. Where do you draw the line who can profit from it? Until it is legal to produce any weapon someone somewhere in the chain will profit from it. In a capitalist setting this cannot just vanish.
I have been to some shady pubs and nightclubs in my life, non of them had so much violent people as a linux bugreport thread.
DIY is like that. If you look up how to make a birdhouse they will tell you you need a saw, a hammer, nails, drill, paintbrush and something to measure with. Having a 3d printer and a soldering iron nowadays is pretty low entry, you can get into it cheaper that buying the saw, hammer and drill for the birdhouse. You don’t have to buy the bambulab printer and the weller / hakko iron. You can print this case on an ender 3 you found in the dumpster. Or pay 10 bucks for someone and they will print it for you. On the other hand you will have a device you can infinitely repair unlike the kindles that are kicking the dust every few year for everyone.
Sssh… Everyone lives in default country
Just use notepad++ with wine like any normal person do
