I don’t care that developers have to pay 30%, it makes no difference to me. If that fee went away… it would just give them 30% more profit.

In a lot of cases prices would go down, that extra 30% makes app development often pretty unprofitable if you aren't the store.

And a lot of things just aren't available on mobile because of the cut. Most apps which offer movies or books for sale for instance only let you view them on the phone, you have to buy on the web.

I think the argument here is that there's less good apps because it's a difficult market and your profits are being garnished too aggressively for it to be a viable option when seeking investment for novel ideas.

It's not about "having less profit" necessarily, it's about it being a more risky business with a lower potential ceiling making investment less likely and thus: a dearth of Apps.

(reading charitably, of course).

Grocery stores on average make ~1-4% profit on revenue. Hungary has a sales tax of 27%. Do you think that if Hungary eliminated the sales tax that Hungarian grocery stores would make 28-31% profits?

Is this the civil rights struggle for middle-men and compradors? You lack a preference that your money go to people who work as opposed to people who don't work and stand between you and the people who do, collecting tolls?

Developers getting paid better is a good thing, surely?
