It does matter whether they do. It’s impossible for Epic to have a valid complaint (and the fact that they both throw a tantrum at every company who doesn’t just give them exactly what they want, and actually do behave anticompetitively by using their market position with UE to try to force people onto their fucking disgusting excuse for a store tell you they don’t) unless Steam is abusing their market position to make competition impossible.
“We can’t be bothered competing” is not a valid legal argument.

Having that market position is what defines a monopoly.
Abusing it is a crime that only a monopoly can commit.
Whether they do it or not is not what makes them a monopoly.
