"Exploit their near-monopolies". Except Valve doesn't "exploit" their near monopoly, I don't see Valve buying exclusives do you? They just provide a better product. Most importantly, they provide a better product then piracy. That is the bare minimum a games store on PC needs to reach and Epic does not reach that. Epic isn't failing because of Steam, it's failing because why buy a $60 game on a featureless store that launches an .exe for me when I can just download the .exe directly for free? If Epic wanted to provide a better product, they have billions of dollars and hundreds of devs to make that happen. They just choose not to.

but I think it’s better that game dev studios and app developers get money instead.

This tired old argument... There's absolutely no evidence that the extra money these companies get from the Epic cut doesn't just go straight into a Bobby Kotick yacht or some shit. There's a lot of grubby hands in-between the store platform and the actual dev teams and maybe I'm cynical but this "trickle-down" model of economics seems kind of far fetched.
