The client is basically irrelevant in this day and age. Anyone could build one better than Steam and it wouldn't even be hard. I only bring it up because it's what everyone talks about when defending Steam. Like it's still 2024 and these things are hard. Steam's only remaining value is its network.

No sir. Trust. Steam has earned trust from their customers. THAT is what the 30% cut pays for. Trust that we wont get scammed. Trust that it "just works". Trust that the service provider keeps our interests in mind when making decisions, not just the shareholders. Trust that Valve is in it for the long haul and our library purchases won't just poof on us. That doesn't mean there isn't risk, but there is trust. I can't say the same for Epic.
