There’s a difference between having a monopoly and abusing it
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.
