But manufacturers can choose not sell through Walmart, Amazon and sell somewhere else.
Apple does not give option to side-load, 3rd party App Store etc.... Where Google has no problem with 3rd party App Store.
Anyway, I refuse purchase anything through in app purchase. I have problem with how anti-competitive Apple is.
I rather take risk to side load apps then purchase staff from App Store directly.
I would rather pay developer directly, not willing to take my money to Apple, because I have issue with 30% cut.
If Apple wants to open store to sell application, they are the one should eat the cost.
