Netflix has it on their cheapest tier. Prime already has ads but for their own content only. I don't have Hulu. Either way, you can always just pirate stuff with Sonarr, Radarr, and a Usenet server account. Black Friday is coming then you can get huge discount on Usenet server account / block accounts, Torznab/Newznab server (you can use SpotWeb, too), VPN.
If you've been paying attention to the industry you'd know driving customers to bit torrent is suicidal.
