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 problem appears to be the expiry of a technology certificate licence from a third party which Logitech appears to be unwilling to extend.
Logitech informed buyers of the Link that those whose devices were still under warranty could receive a Harmony Hub, a device that can function as a replacement.
Owners of the device are unhappy about the development, judging by the company's support forum.

"Why would we ever purchase another product from Logitech after this. This proves all of our Logitech products are at risk of getting bricked out of nowhere. What's to stop Logitech from pushing a firmware update bricking a keyboard (or any other Logitech product for that matter) we purchase?"
