I recall they had to upload The Simpsons in its original format after about a month, they tinkered with it and it meant that in plenty of episodes the gag wasn’t on screen as it was chopped out of oblivion by them messing with the ratios
Yes; they put the whole lot up in 16:9, and the cropping meant that sight gags involving the top and bottom of the screen were butchered - the example which did the rounds showing how bad this was was the Duff brewery and the tanks of different types of beer, with the 16:9 cropped version losing the fact they were all filled from the same pipe.
The only affected seasons 1-19, though, as from season 20 onwards the Simpsons was 16:9 native.
Having seen the screenshots of the windowboxing above, however, I dread to think how they’ve fixed the Simpsons!
Distributing illegal streams is a breach of copyright law, as opposed to an infringement of rights. It’s a crime basically, not a civil dispute so there’s no need for anyone to demonstrate loss.
Not that whether it actually aired or not is relevant to a demonstration of loss anyway.
The rightsholder can normally bring a civil claim too for damages, whether or not there’s a criminal prosecution. Certainly against big infringers
