I'll happily pay to have a game on Steam vs getting it for free on Epic. Steam has been a good experience for me the past 2+ decades :)
It would be under a 'most-favoured nation' type deal, after an initial launch period (exclusive distribution for 1 year, say) if my distribution service pays the same per-view amount then I can stream/distribute your media regardless of your deals. If a producer/creator makes a work available they are required to allow it on other registered channels (no setup cost beyond actual price of downloading the content).
Essentially make rights holders honour the idea that they'd make works S available if only people would pay.
Refuse to make a work available and you'd get a warning, then it enters the public domain. The copyright deal is "things enter the pubic domain after a limited monopoly to allow recompense", enforce it. So, if eg Netflix/Sony/BBC/etc stop offering their back catalogue then the works enter the public domain.
Unfortunately literally everything is wrong with EGS specifically.
Their stance on intentionally not having user reviews because consumers shouldn't have power to react to publisher or developers decisions.
Their giving away games for free and then revoking licenses then removing them from accounts even though it was purely their own fault. They were most successful company ever back then and could certainly eat that loss.
Their shitty account system that certainly got hacked multiple times because it's the only gaming platform where someone constantly trying to access my accounts even though I'm Linux and cybersecurity nerd with random 32-char passwords. They also dont have straightforward way to change account region without trying to deal with their shitty support.
Tim Sweeney decided to make a platform to fuck over gamers and we gamers returned favour.
