Quantum field theory conserves mass-energy, so the new mass is coming from the energy in the Higgs field itself. It settles to a lower energy state and basically transfers that energy as mass to all of the particles that couple with it. Since it’s mass-energy and not just mass that generates gravitational distortions, the large-scale gravitational evolution of the universe probably won’t change, as this just moves things around a bit. It’s not creating energy out of nothing.
If it’s dangerous to repair it, it’s dangerous to own. That’s the domain for regulations by the government, not arbitrary software restrictions by software manufacturers.
They don’t implement these to keep you safe. They do it purely to make more money.
