Apparently you cannot grasp the fact that the potential danger does not guarantee a bad outcome..............just like driving 150mph on the expressway doesn't necessarily mean you're dying because of it.

Actually, they are quite correct for the majority of cases where a side pull is utilized.

Did anybody state that "every customer dies"? Or is this your own conclusion without any data?
The rating on the spring compressor has nothing to do with how the unit is utilized. You'll find multiple exclusions in the instructions regarding how the manufacturer mitigates risk. There is a sizable risk that the spring ejects itself from the external compressor if two of the units are utilized. It's the nature of the design.

Nothing much at all. The unit has internal plates that pull on the spring and the plates cannot disengage when force is applied to them.
The M/B front springs require almost full compression until the coils are flattened against each other to enable installation and removal. The force required for this is well over 2500 lb.
