"customer" is a much better term IMO. It indicates this is ultimately a transactional relationship where both sides have certain responsibilities. The customer the responsibility to provide the money, and the provider receiving the money has a responsibility to provide the customer with something, products or services, of value that makes their lives better.
"user" is a worse term. It suggests that the "user" is simply utilizing the provider's products/services, and therefore they can't really complain about whatever the provider chooses to do in return, because the "user" can simply stop using.
It's also not a coincidence, IMO, that drug addicts are also called "users" since "user" implies a one way dependent relationship and that's what all the tech companies have been trying to create.
