• Netflix added almost 30 million subscribers in 2023 after cracking down on password sharing in May.
• Customers balked at the idea, but in the end Netflix prevailed.
• Netflix also could roll out more subscription tiers to add more subscribers, economist says. 

When Netflix announced it was mulling a ban on password sharing a few years ago, subscribers immediately balked.
