This applies to all IoT device (such as lamp, fridge or door)
This is a sad story for that guy but I admit that it made me laugh a bit. He should have made a research about the gadget first like if it's easy to hack by hackers or not and if it is connected to the internet before buying. I guess he learned his lesson now. It is better to buy offline things like that.
Unlike Bitcoin hardware wallet, i doubt there are many articles/review about security of this kind of gadget.
Companies that produce sensitive things like a 'Chastity cage' need to ensure that data breaches (hacks) are either impossible or when done, they do have a quick solution to solve the issue, or else quite a lot of users of such products will run into trouble sooner, rather than later.
Even company such as Ledger where it's product is about security have security vulnerability, so i wouldn't expect this kind of company have good security.
