The really unfortunate thing is that Insteon predated internet based smart home infrastructure. The protocol was completely local and almost all devices work offline.
Insteon could have been an example of how to fail gracefully by updating their hubs with mDNS support and updating their Apps to use local discovery and the already existing local API that all Hubs support. They could have sent a farewell email to customers and given them a solution that would have worked for a few years at least.
Instead they squandered whatever limited resources they had left and then shuttered their service abruptly and went into hiding leaving everyone in a lurch. They couldn't have even bothered with an email notice a month ahead of their shutdown.
