This isn't a good analogy. The good analogy would be Samsung using part of that space to say "You can also order from samsung.com for cheaper".Analogy...
Just imagine if a company like Samsung wanted a physical space in a brick and mortar store like Best Buy. Now Best Buy offers companies area within their store for a price to keep that area. other companies like Apple and Google agree to pay to keep that space but Samsung, because they have a hype new phone and loyal fans, think they don't need to pay, or instead try to bypass Best Buy getting any of the sale while being in their store because they feel that Best Buy is asking for too much.
So am actually on the side of Apple in this one, greedy, Steve Job turning in his grave bc Apple pen, Apple. Down goes Epic
Come to think of it both MS and Sony now allow stuff bought from outside their stores to be available in Fortnite which they don't get a cut from. If this is why Apple blocked them why would any consumer defend having to pay more. Only Apple fans.
