Don't get me wrong; I'd be a benevolent Ayatollah, and wouldn't

Knowledge is power. If you KNOW which is the better bulb, there is the
temptation to mandate its use (witness that exact fact). People should
gather their eggs in whichever basket they choose, put them in their
pockets, or wrap them in a handkerchief and carry them over their shoulder.

study this."
