Because mass surveillance is bad? I don’t want my printer to send everything I print to private companies

I am ok with someone not being able to print out a gun and then blow people away with it.
And if mass surveillance bothers you, then you should get rid of your cell phone.

Even if you are somehow ok with the surveillance, there are still issues with copywrite. I’m pretty sure it would be pretty easy for some large company to seal ideas or to prevent you from making replacement parts for stuff that you bought and paid for

Yeah but not everything I leagally buy and pay for can be used to murder people. For example, if I print out a battery cover for my remote control I then cannot go to a hotel room in Las Vegas and massacre 50 people at a country music festival with it.
