I'm angry at Netflix because of the 4K nickel-and-diming, which is IMO far worse than setting password-sharing limits. Why is 4K $13/month more than their cheapest ad-based offering, and $4.50/month more than the standard package? This is a truly ludicrous markup on something that costs them literally pennies in terms of infrastructure and network bandwidth each month. It's roughly akin to back when phone companies charged ridiculous amounts each month for Caller ID or SMS messages, even though the network was designed to carry those at virtually no cost. My other streaming services don't charge extra for 4K, and it's quite obvious that it costs Netflix virtually nothing compared with the other plans, and so it's an obviously bad-faith pricing strategy that just makes them look bad.
