That doesn’t say anything. They’re not complaining, but it doesn’t mean they won’t benefit from Steam taking a smaller cut.
Well I’d also profit if groceries wouldn’t have doubled in price but we can’t all have what we want.
I can only repeat myself: Paying steam 30% of your revenue is next to nothing compared to what publishers are usually taking from an indie dev.
Are all publishers like that, to all devs? You and I can’t say. If all the money goes to Steam, it is a blackhole for the money. It is money that doesn’t go into the development and marketing of a game.
As someone that has assisted indie developers for years, I don’t think I’ve ever heard of a publisher that didn’t borderline extort his devs except if the head of the dev studio was playing golf with the CEO of the publishing company.
