Restricting account sharing or jacking up prices would be a bad move of tremendous proportions, especially considering the number of competitors Netflix has and the rate at which Netflix is dropping distribution contracts.

I'm not particularly attached to Netflix itself and would be pretty easily driven away to Amazon Instant Video or Hulu Plus if Netflix stopped letting me share my account or kicked up the price.

I'd say they have to know it's a bad move, but then again, Qwikster happened.
