paying for store exclusives mostly. it was a big deal when borderlands 3 dropped in 2019 and again with alan wake 2 in 2023. its kinda hypocritical when you keep talking about competition and how its important to fight monopolies then come up with a $150M exclusivity deal instead of actually competing with steam.
Setting aside whether paying for store exclusives is right or wrong (personally I don't see anything wrong with it), what does that have to do with the Apple discussion? The problem with Apple is specifically that they use their dominant market position to force anti-competitive terms on other companies. Has Epic been bullying companies into accepting their deals? You can sell a game anywhere, Epic has no leverage in this respect.
