Downloading a Netflix show is not as easy as downloading a YouTube video is not like you go Netflix downloader put a link and download the video easily. Actually as it's was expensive for the piraters to get the show they only offer it with ads. Maybe you can find it with torrents but series are less common to find than movies
Go to literally any private tracker and you’ll find that the vast, vast majority of pirates just do it for free, mostly because they like doing it. And I guarantee you’ll be able to find basically everything, including TV shows, and if you can’t it’s usually a request away.
Mostly the only expense the pirates have is the cost of the media itself, so subscription for the streaming service or the cost of Blu-rays or movie rental.
It may not be as simple as youtube, but ive literally never not found a pirate stream for a netflix show within 10 minutes of it being released + the run time.
