Because the experience of gaming on Steam Deck's SteamOS is better. Because I already have a MacBook and occassionally want to play a round of Civilization or Victoria 3 on it. Removing OS silos for gaming is amazing, Valve really opened the floodgates with Proton. Windows, Linux and now macOS all being able to run same games is just great.
