We've all heard this anecdotally. How much direct knowledge do you
really have of the inventor's greed and disdain for humanity?
Even if he lobbied to have the device made mandatory, maybe it
was because of his own blood-draining experience and was completely
altruistic.

Meanwhile, manufacturers of everything we consume lobby AGAINST
consumer safety, encouraging the government to let them use more
dangerous components and make more wasteful products. Do you have
a car or truck? How altruistic do you think the vehicle manufacturers
are?

I however can't get over the greedy inventor's attempt to legislate his
device into every saw in the US. When his invention wasn't snapped up by
all of the major manufacturers as he assumed it would, he lobbied to
make it illegal to manufacture or import saws without a safety device
(his being the only one that would meet the requirements) installed.
