Profit is how our portion of the world functions. Its called capitalism. Someone makes a product or offers a service which I want and I pay them for it.
If you don't like Apple products or the way that Apple does business, then by all means move on. And if Microsoft is your cup of tea because you believe that they are somehow more magnanimous in their business plan, feel free to choose them.
But we can do without your pompous announcement of your personal feelings and decision. Your behavior here makes me uncomfortable and unwelcome with my different feelings about Apple's products and services.
And you are violating the Terms of Use which you agreed to follow when you created an account to use the Apple Support Communities. You agreed not to criticize Apple's product and/or business decisions.
And did you stop to think that it might be Spotify that made a business decision not to offer their product through Apple? That way they keep all of the profit, rather than splitting it with Apple, who gets a % of all sales through the App Stores, including in-app sales.
