You associate everything that can be bought with cryptocurrency as a scam? It sounds like you haven’t even read the post. I spent a lot of time making it easily accessible here on Lemmy. You don’t even have to click the link. Just scroll-up and read :)

How exactly did you come to the conclusion that this is a scam? We’re a fully open-source hardware & software project that’s been around for a few years. If you don’t want to buy from us, we go out of our way to help users build their own 3D-printed BusKill cables (currently in prototype stage).
