The only thing worse than a customer that constantly calls and requires attention is one that doesn't call at all and finds your product or service useless. If the customer is bothered enough to spend his/her valuable time on your product, that means you have some value. I would much prefer this over a customer who doesn't trouble themselves to spend any time at all on my product and then mysteriously cancels later. Yes, customer support has a cost. So does marketing and getting customer feedback as part of an MVP process. While I cringe when customers are demanding, I also realize how valuable it can be. But I make sure they pay their bills as well. And if I have a support contract, I make sure they buy it -- even if they squeeze the value of that to the last drop.
