If Epic had required developers to, say, sell games 15% cheaper
Epic cannot do that because
In response to one inquiry from a game publisher, in another example, Valve explained: “We basically see any selling of the game on PC, Steam key or not, as a part of the same shared PC market- so even if you weren’t using Steam keys, we’d just choose to stop selling a game if it was always running discounts of 75% off on one store but 50% off on ours. . . .”
However, Epic regularly offers coupons out of pocket. Right now you can get 33% off any game above $14.99 or the regional equivalent, as many times as you want, even if the game is already discounted by the publisher. You also get 10% as cashback.
In the Epic trial, Google made some of the same arguments as those used to defend Steam, like the presence of competing stores or the claim that it wins people over by the quality of the product.
Many of the articles do have references on the DRM status. Here's an example indicating verification by a staff member. I personally tested a bunch of the games for DRM and noted it back when I contributed. Until recently, most of the games released on Epic were DRM-free. Even the Sony games were notably DRM-free on Epic before they were released on GOG. Nowadays, it's more common for the new ones to use EOS and have it function as DRM.
Those stores don't challenge the monopoly, so they don't trigger anyone. They get praised but you'll have a hard time finding anyone who regularly uses them, let alone as their main gaming platform.
Epic's current approach to reviews is arguably better anyway. There's no toxicity, incentive to troll to farm points, and it's randomized, so it doesn't enable review bombing.
It's all in the realm of "what if". Sure, it could attempt this or that, but it hasn't, nor is there any guarantee that it would fly. That just brings me back to the original point of when a company that is not partially owned by the Chinese actively works to please the Chinese government to further their business interest but I don't see much of that with Epic. If you look at some of the other companies in which Tencent has a large stake, like Dontnod, there's absolutely no sign of the Chinese agenda in the games either.
