> As a consumer, I don't care if the fee is 30%. I have no idea if that's a lot
I think you're right about this particular example. But that's because rebelos identified the wrong problem. I would identify a different gag as the problem -- Apple prohibits you from directing your customers to other payment methods.
"Make your in-app purchase as conveniently as possible, right here and right now" vs "Pay 25% less by visiting our website" would kneecap Apple's app store revenue. Itemizing the fee is pointless.
You're absolutely right that this is another angle that could be looked at. A third argument, particular to Apple, is simply that there is substantial harm to the consumer when a company maintains a stranglehold on software distribution for what might reasonably be considered a general purpose computer.
However, I vehemently disagree with the insinuation that disclosing the fee wouldn't provoke market forces to lower it to some more reasonable percent above cost. Sure it's a duopoly at present, but I suspect that might be enough to get competitive forces working properly.
100% is a fairly normal markup "above cost" for each step in a supply chain; it also makes Apple's 43% markup look modest.
And then you get into unresolvable arguments about what is and what isn't a cost.
You're absolutely correct that Apple is adding no value, which is a bigger reduction in value added than the reduction in their markup. But the problem isn't that they're applying an objectively high markup. They aren't. The problem is that there's no reason for them to be involved at all.
For iOS it's essentially impossible, from my understanding. But there's stuff on android to let you install apps, after all?
And if you want your users to install your app store, they'll have to know where to go and tell the OS "I want this installed, it's not malware".
And every time any single app through there requires an update, it must be manually approved and installed by the user. Google's evergreen background updates are exclusive to them.
And if Google Play Protect decides you store is malware because it distributes apps that Google thinks harms users, any user with (the heavily pushed) Google Play Protect turned on likely won't be using your store for long.
But it is technically possible.
I cannot practically create my "Awesome Store" where I have the best ranking system and I ask 0.1% for fees.
As a consumer, I don't care if the fee is 30%. I have no idea of that's a lot or just the right amount of money for the services that the stores provide. I don't know if it makes the app devs life much harder or if it's just a slight inconvenience.
Do you know or do you care who is making the profits (and how much) when you buy a coke in your local grocery shop? I don't, and no matter of math and public information could make me care about it as a consumer.
