Not all consoles sell at a loss. Nintendo outright sells for profit, and the ones that didnt are the WiiU and thr Virtual Boy, and I don’t have to remind you how those sold.
And we are also at an age where even Valve is in the console space. They sell the steamdeck at a severely lower price point compared to its competion.
Look at the ROG Ally, Lenovo Legion Go, Aya Neos entire catelog, GPD Win 4, Ayn Loki and a bunch more.
The argument about consoles selling it at subsidized price is justifyable means your saying Valve is in the right to given they are now in that market.
