This should be a lesson about providing a product versus providing a technology.

Ubuntu is "like Windows but not" which is mostly relevant to people boycotting Windows. Steam Deck is "a gamebox" which people who already like games might want to buy. Bazzite is "a thing that turns your computer into a gamebox." Of course, people don't actually want gameboxes either - they want to play games - but it's a few steps closer.

No, but that is what they will ever get from OEMs selling PCs at computer stores used by normies.

Also lets not forget those distros play Windows games, because hardly any studio bothers with native Linux games.
