He argues if a better launcher emerged it "would still be of no interest to Steam users"
What part of that sounds like “no reason” to give such a service money? If the guy in the article was talking about Epic I’d be inclined to agree with you, but he’s talking about a hypothetical service that’s better than Steam. I’m inclined to agree with him too, it would be very difficult to make a better service than Steam (he’s obviously wrong for thinking you could vibe code such a thing) but even if someone did at this point I have so much of my gaming life on Steam that it would be difficult to switch.
It reads to me like you’re arguing with Tim Sweeney more than the guy in the article you’re responding to.
