I'm not believing it. Those folks are using Android boxes, but they're not from Google.
I'm sure someone followed instructions they found on Medium and want to show it off to their friends. That's fine. Those aren't the majority of users though.
For half the price of a Chromecast, Android STBs are the 'hit'.
most of my friends are not into tech, yet they all own chromecast for exactly the reasons I cited. your milage may vary, but you have no reason not to believe it.
No clue, I'm on a Mac and no knowledge of Nvidia Shield. Plex is great for a lot of things but it's not perfect, has a lot of format support issues, and isn't as direct and fast as choosing a Chromecast Renderer in VLC
