For instance if the EU or the DOJ were to require Apple to change their policies, we could say Apple isn't forced to do so, as they still can refuse and "just" pay enormous fines until bankruptcy.
I'm not sure what we would call "force" if we take that definition.
How unchivalrous of them.
I have no earthly idea what Apple has done to earn 30% of the sale of an eBook by Amazon for the Kindle.
I have no idea if the cut is 30%, but that's the same cut that Amazon takes from an author when they sell a Kindle eBook (and sometimes that goes as high as 70%). What on earth did Amazon do to earn that much of an author's sale...
I have little sympathy for Amazon, the largest retailer in the world, trying to play in someone else's playground. You can buy directly from your Kindle if you really have to have that browse-and-buy experience, but the iPhone app really is more convenient, isn't it?
For instance if Apple had to pay a global total of 2 millions of fine every year for their AppStore policy, it would be rolled in as cost of doing business and they'd keep ignoring the rulings for decades. If Amazon only had minor punishment for breaking AppSore rules they'd do it yesterday.
A binding contract is only as strong as its penalties, and in that regard we can see laws a form of contract and vice versa.
About as hard as opening a new phone network rivaling ATT back in the days, apparently.
If neither Amazon nor Microsoft couldn't do it you know it's not a matter of money and willingness to do it.
If you're referring to the Nokia acquisition, it was way past prime and relevance, at a time when Chinese makers were already on the rise.
Fines are not an exchange of value, even if some firms attempt to treat them that way. They are also not subject to agreement. They are risk and can be arbitrary.
So no. They are not the same.
