TBH I have a subscription to multiple streaming sites, but I usually torrent what I want to watch anyway.
I paid to watch it, I'm simply choosing to watch it in the way that's most convenient to me. Sometimes Netflix forgets to supply the video in the quality I paid for, so I'm simply helping them fulfill their contract.
But on page 69, section 420 of Netflix's EULA, it says that you may only watch videos in the quality you paid for if your device is capable of supporting their shitty hardware DRM implementation, where if you modify any part of the system, it becomes invalidated.
Therefore, you, the consumer, are in the wrong for not reading through and understanding the entirety of the license agreement before paying extra for a service that didn't make that limitation obvious before receiving payment. Nothing legally-dubious going on here.
