Competition is usually always a good thing, but sadly no launcher has ever brought anything new to the table that Steam hasn’t already been doing (they usually just bring headaches).
Epic doesn’t want to compete fairly (by providing a great user experience, etc). They want to compete by paying for exclusives & bribing users with free games. Obviously this hasn’t worked because they are loweri g fees, likely to try to get the growth they just aren’t seeing.
Like Steam is doing?
I don’t think their cut is them being greedy.
Your plan might not be economically feasibile, because companies need money for growth (new products, R&D, etc), so only charging enough to run is not possible.
Steam is probably doing a kindness by not charging an infrastructure fee every year to developers, that shiz would probably really expensive.
The cost of the cloud features they provide is likely, usually, understated. Just the bandwidth costs alone of allowing your game to be downloaded whenever the user wants and however many times they want is expensive enough. Add on cloud saves and all the other niceties…
All that is just to say that Epic is likely losing a lot of money here just to try enticing more developers to move over, and maybe bring some customers too, but it’s not gonna work. They are lucky the fortnite piggybank lets them do this, but it’s not smart by any means.
