Again, depends why. They went bust or are closing? OK that sucks, but it happens. Can't really be helped. Even if it's a hardware thing it's going to happen

Again, depends why. They went bust or are closing? OK that sucks, but it happens. Can't really be helped. Even if it's a hardware thing it's going to happen if there's a server-side component rather than entirely stand alone. Best case release some code, specs or open source to enable some hackery to keep hardwareThing viable. We got bought, OldThing is boring so it's closing in 4 weeks, we're truly excited to be working with FaceGoog on the future of NewThing. Seriously not ok. People should be writing Medium articles about it. And yelling.
