Have you really never had any of your data leaked and plastered all over the internet for all eternity? Of course it's a credible threat. Cloud service operators should finally get it into their heads that they can go E2EE or GTFO.
better question: why does this device even need a cloud? Why does a Roomba need a cloud? Why does a smart lightswitch, a doorbell, or any other of these devices need a cloud?
There is no reason. It's dumb. Sync over wifi to your computer and phone and use MDNS to discover them.
