Regulations are put on companies after their freedom of choice; when abused, starts harming people. I think IoT is a perfect example of this. Today the manufactures have a great deal of freedom. Their lack of self regulation will require others to step in and regulate them.

On the matter of vigilantes: This is a complicated topic, but I support them doing this, even if it harms myself or someone I care about. If this problem is not stopped sooner than later, it will explode into a much bigger economic and/or societal issue that will be difficult to contain. I have warned the people I care about already.

The current state of IoT is a complete lack of responsibility. I would even support someone bricking every piece of machinery they can, including cars, heavy equipment, power plants and anything else that was built without proper engineering.
