Nintendo, please sue me! I would love to help establish more case law here
Right now i have a laptop connected to my TV to play steam games that support controllers. I'd much rather just have another USB-C to HDMI converter plugged in to a device designed nearly completely to play games.
A huge use case for me would be using wemod/cheatengine and in general steam workshop. The second biggest reason is shovelware. On the switch if i buy a game because it looks good, AFAIK i can't refund it if it's actually a garbage game. On steam, i've requested refunds after playing (some*) games for several days.
* mostly incremental/clicker/idle games, because they're designed to be crappy to start out, so 2 hours isn't even enough time to expose 1% of the content or gameplay.
Citation: I own a steam deck and an ROG Ally. The Ally has the best controller on the market but it's hamstrung by the screen simply having too many pixels. Well, that and Windows.
I have a steam deck. So far, I have bought roughly 5 switches. One for myself that I gave away as a gift, and 4 OLED switch gifts.
After seeing what Nintendo is doing, I will never buy anything from them ever again, nor will I purchase Nintendo products as gifts for anyone.
They are greedy and immoral. This is the consequence of attacking open code.
