>The market for stand-alone "streaming boxes" is.

I've already addressed why it's not simply "stand-alone" streaming boxes, and why it also includes the streaming software included in many of the Smart TVs being sold, their software ALSO becoming subpar in the time they spent to pursue content creation alongside their hardware becoming undesirable.

(also the market for standalone boxes/pucks/sticks isn't "on its last breath" either)

You keep suggesting that Roku on Smart TVs works by "launching the app" when that's not how that works, too. You don't "launch the app" on a smart TV powered by Roku. You just turn the TV on. Roku is the software that makes the TV go. You seem to believe it's an app - it's the OS.
