I agree with you, but I would say you can’t assume everyone has the same goals. I can tell you, my Nintendo friends are not idiots nor mindless zombies. They simply are not interested in learning about how the other options work, and I would say that’s totally fair.
I have a dear friend who has most of his games on Steam, but still, he told me he prefers the Switch. “Why?” I asked him. “Because Nintendo makes exactly the kind of games I want to play, and because unlike with the PC, I can just pick up my Switch and start playing” he answered.
I have a ROG Ally with Bazzite (so, basically equivalent to a Steam Deck) and I have to admit that, while 90% of the time every game works out of the box, sometimes some games misbehave. Although, to be fair, this only happened to me with Epic Games games ran through Heroic.
I would say it’s totally fair to prefer Nintendo. It gives you great games that don’t require tinkering. If that’s what you want, then Nintendo is a great option for you.
