While I use ubuntu derivatives on my computers, their IP and somesuch is a crap. So when it comes to making embedded designs, I'm really much better using Debian. There are far more picky about IP things and do not expose any weird/non-reasonable requirements eiter.

So if Canonical wants to hurt their systems adoption: okay, I think they acieved it. So at least some part of Internet Of Things going to be Debian based instead. Whatever, Ubuntu is just too risky/troublesome to use it in any commercial application. And it is their IP policy to blame.
