At this point, Epic is probably so desperate to get a significant growth for their store that they accept anything that isn't a scam. It's remarkable how many popular games are still missing on EGS.
They are missing a shitload of new good looking games, games that are releases on both like B4B and BF2042 have been on Steams top seller list (B4B has been on top on Steam since the release) and a ton of other good looking indie games and bigger games only have Steam store pages or announced for Steam (Choo Choo Charles, Propnight seems to have made quite som splash in social media to give a quick example) and a lot of bigger games for the next few months not coming to EGS (Elden Ring, Halo, Forza etc.)
Remember, Valve has been in this game for so damn many years, they know what's going on, them being private and self-funded also allows them the creative freedom to look at the competition in a way GOG, Epic, MS etc. can't. Like, Epic is private, but not self-funded, the majority of companies are not self-funded.
Everything points to that the people working at Valve are passionate PC players themself in opposite to a lot of other companies having their own storefront on PC and Valve being both private and sef-funded means that the one people they need to listen to is the end-user - the people who plays games on PC. Other companies can't do that. Epic need to listen to investors and others funding them.
Valve can do whatever they wanna do as long as the laws allows it, Epic etc. can't. If Tencent wants Epic to start a paywall for online, Epic needs to negotiate and disuss that, if a company approached Valve with a paywall for online plan, Valve can tell them to fuck off.
