I wonder if this will cause some people to actually share accounts more than before, not less. For example, I pay for my own account, despite my brother asking me to share with him (we're both employed and in our 40s, and I feel like we should pay our own way). He eventually set up an account and shares with our parents. So between us, we are probably paying about $40/mo for Netflix. With this new system, I might decide that I should jump onto my family's account for $5.99 or whatever, since this type of sharing is now blessed by Netflix. That would cut their revenue from our family to $32 (an extra $6 for my parents and me) from $40.
