Steam is a monopoly because it provides a better service. If you don´t like how much they take, you are free to sell your game to the 5 Epic Games Store users that there are out there
tho even if all of us know steam is providing good service, not sure how out in the court the listener and judge could understand how good those services are rather than just focusing on the 30% stuff
yeah i can possibly pay a little less for games on egs, but the launcher is just DOGSHIT (how does the third party heroic launcher have better ui than that), and the service may as well not exist
