Epic only cares about creating their own store and charge their own fee to developers
I watched that video from end-to-end and it makes amazing sense! Epic is way above and beyond the simple-mindedness that's playing out in these forums. They have a very sophisticated and long-term game in play. This whole thing has been planned months, maybe even years, in advance.
I don't think that Apple's 30% can be compared to VISA/MasterCard's 3-5% since Apple continues to invest into Research and Development year after year after year. That takes money. What are VISA and MasterCard doing each year to advance the industry that they are in? Not much. Maybe something every 10-20 years.
