You're making assumptions with no context. This is how TechCrunch cites it:
> “We love people sharing Netflix whether they’re two people on a couch or 10 people on a couch,,” Hastings said. “That’s a positive thing, not a negative thing.” To illustrate this example, he spoke of how a parent may share their login with their child. And when that child grows up, they will usually subscribe to Netflix, too.
Unless the couch is spanning multiple households, I don't see evidence for the claim. His keynote makes no mention of this so I assume it's mentioned somewhere else but I can't find the source. The CNET site is truly garbage.
Regarding 6 devices, that's nothing today, even considering an average family with two kids. Everyone will have their own phone so that's four. Then you'll have multiple TVs, computers, and possibly one or two tablets. My family of three (one kid), have 10 devices and I don't see that as out of the norm.
