The tamper proof screw is NOT there to protect you, It's there to discourage repairs plain and simple. A warning label is more than adequate on other blenders, why not this one? In fact, there are plenty of dangerous devices I can think of that don't need to be locked down to prevent lawsuits. A lawsuit would require negligence on the part of the manufacture and while you're trying to say by not locking it down it could be considered negligence you'd be wrong. Otherwise I could quit my job and just file lawsuits all day.
Let's not try to defend these companies that engineer planned obsolescence into their products. All they want is to be the sole repair option (big profit margins) or have you buy a new over priced high markup item. Nevermind the waste generated by hrowing away perfectly good products that a simple easy repair would fix.
