For comparison, and hoping that netflix doesn't devolve to that point, I submit Spotify. My wife and I have the "2 people" plan. But it is draconian that only one device be used at a time. So if I'm listening and my wife starts the car, my shower/work tunes shut off. The car doesn't have multiple profiles. Similar happens if she is in the kitchen and starts tunes via voice (bluetooth from her phone understands it is a different profile).

To be fair, Google Play has similar draconian limitations. I assume this is part of their agreement with the music industrial complex.
