Beats paying $500 for a console. You keep adding “on the go”, I’d imagine they would be playing these games at home for the fraction of the price you would pay to play them any other way.
So, the same type of people that care very little about games, when at home, will be the same type of people to go and find a controller, link it through Bluetooth and pay a 15 dollars subscription? How many non gamers do you ever see doing that? It's way too complicated and the userbase is not interested, it just doesn't work, it's an incredibly dumb and desperate business idea.
They want to disrupt the market without even bothering to understand their target userbase. I mean, I'm sure their objective is not to lose billions to gamepass just for the hell of it.
