I understand the concerns. I've tried to disclose appropriately and focused on two things:
1. This is a legitimately new approach. Pretty much everyone I know in the IoT and connected device world is still building a backend infrastructure and coding their own APIs, even for pure analytics apps.
2. A detailed tutorial seemed appropriate so people can see some of the ins and outs of doing this, and to show that now non-experts can do this kind of thing as a weekend project.
Obviously, this doesn't eliminate code or servers. But the big win is that I don't have to deal with any of that. It's like saying Rails wasn't a big deal because all the code is on the framework, or AWS isn't a big deal because there are still servers.
So look, I'm not a PR flack or something, I've been working on wireless sensors professionally for over a decade and I'm just excited to see the work get a easier, because I've spent a lot of the past 6 years building out and maintaining a scaled sensor backend before. It sucked, and I don't want to do it again if I can avoid it!
