This particular company decided to grow financially by cutting apple from a revenue stream. Apple invested billions of dollars in rnd, PR , legal protection, security, servers etc... Behemoth like Epic decided to ignore that, at the same time still using apple services and platforms. Such a simple case to me. The funny part is I never heard from small company that gain traction from apple store that it's bad. It's a social lift for them. But once you grow , you forget about it... and start complaining...
