Re: Makes sense.
It's probably helpful from a continuity perspective as well. Rather than design new platforms based on Linux or Android every time they start making a new smart television, they can stick with this and reuse some code. That is if they remember they've got that code, which has not been a hallmark of other IoT manufacturers.
That said, I wonder how much code can profitably be shared between a smartwatch and a television. While the kernel could be copied, the smartwatch has the problems of limited processing and very limited battery life, while the television is connected directly to the mains and has an excuse for a much more powerful processor. That doesn't mean they can't use exactly the same kernel for both, but one designed for a television might put heavy pressure on a watch's battery and one designed to preserve the resources of a watch might not be as snappy as users of a television would like.
