It is super sad that Mozilla decided to leave this space though (even if trying to pivot FirefoxOS was nothing but trying to buy time). Wish there was a less insidious company trying to get into all my devices.
Also, why "Weave" instead of just using Thread? ( https://en.wikipedia.org/wiki/Thread_(network_protocol) )
[EDIT] - It looks like Weave IS built on Thread, though it's a little sad that it took me so long to figure it out:

My knowledge of the Thread Group's management/scheme layout was lacking, it looks like it's INTENDED that thread is meant to be below one layer of abstraction, managed by different vendors (sillicon labs, nxp, etc)
