In a society where people refuse to have food inspectors and some are being harmed by food poisoning, I think one could argue that there isn't something wrong with that level of action.
I think it's more like firearms. These devices can be and are used as weapons to hurt 3rd parties on the Internet. It's more like firearm owners leaving their weapons in front of their barely-sturdy windows. Then, folks needing weapons keep breaking the windows before firing them at others. The homeowners and homebuilders keep letting it happen.
So, vigilantees concerned about damage to innocent people keep breaking into the windows, stealing the guns, unloading them, and tossing them into landfills. I'd be like: "Stop putting your guns in front of the windows. Be a responsible gun owner." Enough broken windows and stolen guns might incentivize them to do that.
Soft-bricking is hardly comparable to burning something down. More like adding an extra lock and throwing away the key. Inconvenient, but not destructive.
Food safety inspectors have an official remit to do this that is enshrined in statues and local laws. You don't get to just decide for yourself you will shut down some restaurants on a freelance basis.
You'll find it in tons of large-scale (e.g. governmental) decisions at the very least. "is it worth more to prevent X than to deal with the fallout" is a decision that has to be made at some point, and human life / injury are part of that equation.
So, in a way, yes. I do. So do lots of people when they go to urgent care rather than the ER, knowing that the ER could bankrupt them, and they'd rather risk the delay. I don't have numbers off the top of my head, but I don't think it's as uncommon as you seem to think it is.
Most people have wildly inconsistent treatment of health risks and are largely reactionary. Not sure they are a good basis for determining what is ethical/moral actions.
