"Dumbth" needs to be stomped out wherever and whenever you find it.
Even if you can't fix it, it's existence needs to become common
knowledge so other people can spot and avoid it.

But give the company a heads up, a chance to figure out there's a
potential problem with their old machines and to issue a service
bulletin about it - if you get up on a soap box, they're liable to
take offense and sic a lawyer or three on you.

A friend of mine (Not a FOAF) is a repair tech who found a
repeatable flaw in an automated stage light - if you called for a
certain combination of focus position, color filters and gobo screens,
the whole light would lock up solid in whatever position it was in,
and you had to remove power to get it to reset. If this happened in
the middle of a show, it could be a big problem.

The company's initial reaction was to deny there was any problem at
all, there's no way that could happen, yatta yatta yatta. Or at least
till they tried it themselves - then they got very very quiet... They
have since revised the operating firmware on the PROM two or three
times, and AFAIK they send them free to anyone who asks.
