With my Captain Obvious hat on I said digital systems can carry such
data. The case where some cable companies interfere with the original
broadcasters data doesn't demonstrate it is impossible, they don't
affect the quoted satellite case nor others such as DTT

I don't disagree with the cable cases quoted by others, they
demonstrate why I disagreed that it's financially trivial.
Of course I'm wrong, it is financially trivial as they would carry it
if you paid them. It's just highly unlikely to be financially viable

Yes, that was the case with analogue too, they just hadn't found
someone to sell the data to back then. Cable companies will mess with
anything including netflix.
In our case we sold VBI data so I coudln't make a viable case to offer
a USENET service.
