Honestly I don’t know why people think they should be able to publish their software on anything anyways. I can see the iOS/android argument at least because they’re ubiquitous. But there is nothing wrong with how game consoles currently work. It’s a win for Sony/M$/Nintendo, game developers, and consumers. If it wasn’t, then games would only get released on PC (which already allows for exactly what you seem to be advocating for)
I want one with more power in a displayless box I can plug into my TV and make it my only console.
(they tried with the Steambox, but it kinda faltered)
I mean, you're basically describing the mini-pc form factor. I'm not sure exactly where the steamdeck lies but the last couple of years these laptop CPU based systems have been pretty amazing for what they pack.
No need to spend hours adjusting settings and scouring the internet for That One Setting that will make it run smoothly.
Even CP2077 runs great out of the box on it - and it's nigh-unplayable on PS4 level hardware.
The PS5 was sold at a slight loss at launch, Sony got production costs down enough to be profitable about a year later (https://www.bloomberg.com/news/articles/2021-08-04/sony-rais...).
I'm less sure about Microsoft, my understanding is that the Series X is profitable and the Series S is a loss leader. However, both of them can be put into a developer mode and you can run your own (or other people's) code.
