I wonder how much sense that would actually make for them. All the major console makers subsidize their products through game sales and online subscriptions. Valve already does the former, but that’s because they’re a game marketplace and it’s how they make money to begin with. I’m not sure what a steam subscription service (that’s not a game pass) would look like, since Microsoft, Sony, and Nintendo offer online play and cloud saves for the cost of a subscription, whereas Valve makes those available for free.
