A catch is that hydrogen does become much safer in high-pressure tanks, because, when such tanks are breached, hydrogen escapes so fast that it can't react with oxygen fast enough to burst into flame. To prove this, Toyota literally shot their hydrogen tank with .50 cal[1].
Practically no one died in the Hindenberg disaster. There were more people injured than died. Most people involved just walked away from it. It was televised spectacle much more than a factual tragedy.
(It's a bit like saying we shouldn't use AC power because look what Edison did with those poor elephants. It's interesting anti-technological propaganda that made sense socio-politically at the time but isn't that useful to today's discussions.)
