A correctly manufactured chainsaw can be used safely by adults. Products like "MoonSoll and Magic Chems Fuel Bottles" [1], "Tesla Powerwall 2 AC Battery Power Systems" [2] and literally tens of thousands of other products listed at [3] have been determined that they can
not be used safely by adults, and are literally taken off store shelves until the issues can be resolved. It is a normal, everyday occurrence that manufacturers are very motivated to not sell products that cannot be used safely, Hacker-Newsesque semantic nitpicking notwithstanding. If similar liabilities applied to software like Roblox (think "kids committed suicide due to interactions on Roblox" being held equivalently to "kids have been suffocated by this defactive crib"), there would not be a Roblox without effective moderation.
