A year after Logitech screwed over Harmony users, it, um, screws over Harmony users: Device API killed off

You know that Hub that we forced you to buy? Yeah, we've messed with that one, too

Pity the poor users of Logitech's Harmony smart home system: last year they were told the manufacturer was going to brick its Link hub and forced them to buy the latest version. This year, just in time for Christmas, it has effectively bricked that new hub for anyone using it to connect to other devices."
