> open but easy to use devices, like Steam hardware & co widely available

The problem was never the hardware. Consoles and PCs were both a compromise, a trade between convenience, flexibility, price. The easy to use devices from Steam are more console than PC and that's fine. Nobody has a problem with this as long as games run. If the game runs well I don't care about the CPU, RAM, OS, or that I can't upgrade them. I don't spend money on RAM for the sake of plugging things in, I spend it because the system needs it. The Steam Machine is a step towards "consolification" from a PC perspective. The Deck is a true console. So saying "finally consoles are gone" should be more "consoles are dead, long live consoles".

The big problem that only recently got prominence is ownership of the games. Take away the brand loyalty and you'll see that Steam isn't really doing much here. But I care about being able to buy and sell my games, or play them for as long as a compatible system is available. In this regard the Steam store is not much different from console stores. It offers some quality of life features but the core is still missing. It's not my game anymore and this comes with a lot of implications that aren't mitigated by running Linux or having RAM slots.
