But that’s my point, really. The number of total Mac users isn’t that relevant because, given that platform’s constraints and goals, the share of users downloading a game store is significantly lower.

Now with Linux (in the desktop/home use) you have tech inclined people, and every single Steam Deck ever sold, which means the percentage of users installing Steam is certainly higher. This metric of slightly surpassing Mac still paints a picture of very slow adoption of Linux.
