Someone who doesn't want to pay 6 subscriptions, I guess.

if Netflix were smart they'd try to push a network package deal -- where you can signup for disney, hbo, amazon, through netflix and they take $2 or something off each subscription as incentive, users get single billing for all streaming, you'd pay the normal price or maybe get $5 off if you buy all networks for like $50 or $60. disney, hbo, amazon still get their $$ but Netflix makes some off the top, could be all the providers network and create the same deal for each other, but whoever sells & bills the packaged deal gets the extra $2-3 kickbacks.

I doubt this has anything to do with Netflix being "smart".

If anything it looks like Disney may be trying to execute this exact strategy in the future. Look at how they refused to participate in UltraViolet and eventually got most of the other major movie companies to quit supporting UV and join the Disney-owned Movies Anywhere service instead.

I doubt they would play ball with such an attempt by Netflix.

That’s literally what Apple TV’s strategy is

Or people become better at bouncing around with their subscription dollars. One of benefits of moving to streaming is the ease to stop and start the subscription.
