In its initial announcement about the Link, the company had said that those who had a device that was still under warranty would receive a Hub in exchange. Others would have to pay 65% of the cost of the Hub to get one.
The Harmony Link is a device that has a cloud-based system which allows users to control home theatre and sound equipment from a mobile app.
The reason for discontinuing the Link is the expiry of an encryption certificate licence from a third party. Logitech says, "we would be acting irresponsibly by continuing the service knowing its potential/future vulnerability".
In a Q and A, Logitech said it had made the decision to discontinue the Link because it had a small active user base.
The company also admitted that it had, as suspected by many users, censored the words "class action lawsuit" from posts in its support forum.
