Barriers to Churn

These days it seems like the only real barriers to churn -- i.e. leaving one product/service provider for another -- are artificially-imposed early termination fees (ETFs). It used to be really hard to move from one provider to another for a wide range of reasons including differentiated offerings, difficulty in transporting data/information, or even things like not being able to take a phone number with you.
Technology and regulations have made most of those things very easy to overcome. And, with more and more providers offering great incentives for new customers, the enticement to move is at an all-time high. The result, however, doesn't appear to be that providers are working really hard to convince you not to leave -- quite the contrary, they seem more interested in the next person they sign up than the one(s) they just did. And, the natural result is that they threaten you with fees if you leave before your contracted subscription with them matures.
Why not go the other way around? Why not focus on providing customers with what they want and expect from you -- and making sure your enterprise technology "stack" can help you deliver it effectively -- than imposing penalties so customers are afraid to or cannot afford to leave? Imagine building loyalty, providing great service, and effectively communicating with customers as the carrot that makes them want to stay with you, instead of the ETF stick that forces them to.
