Saying it again doesn't make it less wrong. They are in a position where they could possibly use anticompetitive practices to become a monopoly or close to it. Currently they are not, and are not a quasi monopoly either. They simply have created a well rounded service that is preferred by a majority in the PC space.
If you want the store front to take a smaller cut then you can sell on itch. If you want to buy games without DRM then check out GOG. If you like shitty service, venture capitalists, enshittification, and AI slop then Epic has you covered.
