After reading this I thought I'd come into this thread and see a bunch of people upset with valve..... nope of course not.
Seams to me after steam monopolized the market that they went straight evil and greedy.
The cut has always been there. The cut is industry standard, and is still less than if you sell physical. The cut pays for all the infrastructure to get your game into the hands of the buyers, as well as various services like the Steam API stuff to support all your multiplayer, modding, patching and seeing all the data about your users. Steam is hardly a monopoly when you can decide at any point to sell your game elsewhere such as GOG(if you pass the screening test that is since unlike Steam, they don't allow everything, and as every similar process, is extremely subjective so your "quality game that's not an asset flip done in 3days" might still be considered not worth it) or itch.io which I hear has a much lower cut(you decide what the cut is I think?). Probably Discord too now, or soon.
It's funny how some devs talk about the golden days when Steam actually cared and screen games and if you got on the list you'd sell hundred of thousands copies, but that's assuming you made it. If they went back to that like GOG does, you could bet a lot of games wouldn't get in. You needed to get a large amount of people to vote for your stuff on Greenlight so you needed to make a really good game in the first place. And you know what, if you make a really good game, chances are it's going to sell nowadays too, still. In fact people wishlisting your game has the same effect as people greenlightning it, I think?
Also, an interesting bit about the article. Count how many times Discord is mentionned. Discord, who's preparing to be direct competition to Steam. In an article saying Steam is bad. I guess it could just be a coincidence but it's interesting.
