Which same chance is that? Please fill me in, I've never negotiated with Epic's game store.

Zero. It's take-it-or-leave-it. Standard contract negotiation "tactics" these days.

That's unfortunate, maybe neither of them should be doing it?

Is it though? If you create a set of rules for your sandbox and somebody comes along and wants to play in it but only if you change the rules and you say “no thanks”, that seems totally reasonable. Why should you have to negotiate?

The "sandbox" isn't their property anymore, it was sold to the end user when they bought the phone.

Maybe this is one of the fundamental misunderstandings of these arguments: those who think this statement to be true and those who don’t. You bought the phone, you didn’t buy the ecosystem, buying a $500 phone doesn’t give you the right to dictate the multi-billion dollar business.

But it gives the vendor the right to tax you 30% on all future purchases related to that device, even if you disapprove of the job they're doing in stewarding the ecosystem? Despite that there are plenty of other vendors standing by that would be happy to steward it if given the opportunity?
