I vigorously disagree with this. It sounds very confused about economics, specifically prices.
Apple, as every market actor does, charges the absolute maximum price the market will bear for their products and not a penny less. They cannot "make up" any money that comes from unrelated parties (such as their Google payola for search, or their casino games for children IAP revenue) by raising product prices. If they could raise their product prices and have that be profit-positive, they would have done it yesterday.
They could raise prices on phones to make up for a hypothetical "free iCloud+," because the same consumers are the other party in both those transactions so presumably many people would see that the more expensive phone justifies free iCloud services.
Apple doesn't set its prices by saying "OK, we need exactly 83 billion dollars in net income this year, so given that our products cost us 233 billion dollars to make and we have 54 billion dollars in expenses, we need 383 billion in revenue, so now let's set prices of each product to target this."
That $83 billion in net income is just the number they are able to make last year with the prices being what the market would bear. Trying to increase prices to hold it there when a downfall in other revenue happens would depress sales.
That price is much lower than it otherwise would be if the only revenue Apple could generate came from hardware. The opposite incentive exists today, where it actually benefits Apple to sell cheaper razors to make more money from the razor blades.
Not entirely how you've made formed this connection but respectively it sounds like you've confused several things here.
iPhone sales pay for the entirety of Apple's R&D. 10 times over.
