What exactly happened on oil rigs that caused them to be specifically called out in anti-piracy statements on DVDs and other media?

I hope it was unspeakably egregious.

There's a copywrite warning at the beginning of a lot of DVDs explicitly forbidding public showings in hospitals, prisons, schools and the like.

This thread will suck any amusement value out of that particular thought (it's meant for offshore rigs) :
