These “product of their time” things are more disclaimers than warnings. It’s not about people not knowing what to expect from an old show, it’s about the broadcasters protecting themselves from liability or sanction.

It’s like nuts having a “this product may contain nuts” warning on the back. Or a clothes iron with “warning: product becomes extremely hot during use”.

Of course everyone knows these things, it’s to protect from disingenuous people who would claim they had no idea, and would try to sue Russell Hobbs because they burned themselves on their iron.
