But the case being argued is demand for the Steam Deck which is demonstrably high. The counter point to that was that production was low, therefore selling out doesn't mean much. However, the Steam Machines didn't sell out at all so at the very least there is more interest in the Steam Deck than Steam Machines. Sure, it doesn't follow that the Steam Deck will necessarily be a success, but the GP's arguments seem lazy and bad faith, which is presumably why they are being downvoted.
