Re: What to do?
"As the article points out these fines aren't even a rounding error in Apple's cost of doing business."
People constantly make claims like this, but it doesn't really hold up. The Netherlands are fining Apple for their actions in the Netherlands, so what matters is how much Apple makes in the Netherlands. Apple's global revenue is not relevant here. €50 million might be insignificant to the company as a whole, but it may well be more significant relative to the income from a fairly small country. Apple sells hundreds of millions of devices, and there are only 17 million people in the Netherlands in total.
In addition, total revenue isn't relevant even when looking at only a specific region. For a fine to be effective what matters is that it costs more than any benefit gained from the undesired behaviour. So Apple's income from things like hardware sales and service subscriptions are irrelevant here. What actually matters is how much money Apple makes specifically from taking a cut of payments for dating apps. I suspect that's rather less than $378 billion.
Just pointing out that Apple is big is meaningless, and the same applies every time the same comes up for Amazon, Google, or anyone else. Fines are not intended to deliberately destroy a company, they're intended to be an incentive to change behaviour. How much money would Apple lose by allowing Dutch dating apps to use a different payment processor? If it's less than €50 million, then it's in Apple's financial interest to change what they're doing and the fine is entirely suitable. Apple may have lots of money, but they didn't get that way by throwing it away by subsidising unprofitable behaviour.
