I lean towards ‘no’ because I do not see moves on their part to actively attack other distributors
That doesn’t matter. There’s a difference between having a monopoly and abusing it to distort the market. It’s the abuse that’s illegal, not the monopoly in itself.

Sure, but whether Valve fits the definition is debatable. Being highly dominant does not automatically make something a monopoly. At best you could call it an imperfect monopoly/ imperfect competition, because substitutes absolutely do exist, but they’re not mostly close enough to be truly competitive. It’s also important to factor in that 4/5 of the largest games on PC are not even on Steam at all: Fortnite, Roblox, Minecraft, and League of Legends. PUBG is the only one of the top-5 that’s on Steam.

Under US law, yes it does matter, that’s what makes something a monopoly under US law, otherwise it’s just a dominant market position.
