Android makes RMS's GNU/Linux language make sense. It is a Linux, but not a GNU/Linux.
Google's attempt to fork Linux failed and now is mainlined so they can maintain as small a set of patches as they can. Once binder was merged, there is no fork anymore.

Android is basically a build config now.
TVs that aren't Android are probably GNU/Linux. Smart white goods are often Linux. Linux even get used in cars. Some of it under Automotive Grade Linux, but not all. If some random thing has a user interface, find licenses and you can normally see what FOSS went in.
You can do so much with so little, at no cost of licencing or access. Why wouldn't you?
You use things like Yocto and Buildroot to build a image that has nothing but what you need, how you need it.
They can't fix Windows either, so that's not an argument.
Least if it's a Linux system, they don't need to buy any software to sort it out. It's free and out in the open.
