That's their problem, they don't own the pipes either. They don't own the pipes and they don't own the content (before House of Cards). Up to now they provided...well...a useful cute little UI, but it's hard to make a lot of profit for a prolonged period of time on that. So they either go into pipe building or content building. Content building has the better leverage to the large customer base they've got, and in that context producing House of Cards makes perfect sense. I hopes it works out for them.
IMO, licensing and aggregation are the "hard" problems, not UI or streaming or whatever.
They have 30 million users spending $100/yr. Assume they spend half their income on content. That's $1.5bn/yr. That's a huge amount of money, and it's only going to get bigger as they grow and expand into new territories.
Increasingly, Netflix revenue is so high that it will seem inconceivable for content owners to turn them down in a gamble to go it alone and increasingly hard for anyone to compete.
I am extremely bullish on Netflix. I think they have a sound business model with huge upsides and the downsides are hugely overstated.
For 8$.
