Not watching a video, but how is it legal for any company to "sell" something like this? (The video might explain that, but that's my focus of what I care about out of the situation.)

Sure, someone will make a video “this coffee machine killed my wife and burned down my house with my children in it”, and you would say it’s the market working as intended…
There are standards the stuff sold need to meet, even if ultimately you are always “free to not buy it”.
