If that is true then one of those other two claims has to be false:
1. Using the latest months recorded share (Oct-2025 - 3.05%): 4,026,000 estimated "monthly active users" for Linux+Steam.
2. Market research firm International Data Corporation estimated that between 3.7 and 4 million Steam Decks had been sold by the third anniversary of the device in February 2025.
27% of 4M gives us 1M Steam Deck + Legion users. Yet 4M were sold. That begs the question: How could it be? Do 75% of Steam Deck users run Windows? Have 75% of Steam Decks ended up in the landfill? Are the sale figures estimates wildly off-base?
