Have you played with it at all? Mozilla isn't acting as a data broker, they're providing software and a framework. The world of iot doesn't have that many great offerings for private systems. Mozilla is taking their years of software experience and building something decent. I'm glad to see this hasn't been shuttered yet. I've been wanting to move more of my home automation away from cloud based services and this has a lot of potential. (The current best offering I know of is hass)
