You won't get DRM free, because Netflix don't sell you the content, they rent it. Or, more specifically, they sell you access to the platform to stream the rented content.
I'm all for DRM-free purchases, but you're never going to get DRM-free rentals.
Their stuff, and everyone elses, is easily available for download, DRM free, without a fee of any kind. DRM has never stopped that. Netflix knows that. I have no doubt DRM is required for every contract they have with other studios, but they could show they're not fools by allowing me to stream their original content without having to allow closed, proprietary binaries to run on my machine to do it. I have no interest in maintaining terabytes of video and manually managing distribution to multiple device. I don't think many people would. I'd rather pay the $5 a month. I won't enable DRM in my browser, ever.
