I have no idea why this is newsworthy. Epic's own 2019 documents and testimony in the Apple trial showed that the company did not expect the store to be profitable until 2024 or even 2027. The strategy of heavy investment and operating at a loss to turn a profit later worked for Spotify, Netflix, Microsoft, and many others. Even this week, there are headlines like "Elon Musk Says SpaceX's Starlink Achieves Breakeven Cash Flow".
You can't deny that Epic taking 12% revolutionized the industry, with Microsoft following suit and even Valve making some small changes. As Gabe himself said on the competition, "it keeps [them] honest". That's a win for game creators.
For the gamers, we got many free games and I think the Epic freebies inspired Microsoft to offer similar deals with Game Pass, Amazon with Prime, and even GOG recently gave away a pretty notable game, Blacksad, which was uncharacteristic in relation to their past giveaways.
