But without profit the company won't have the means to create good designs, buy the materials needed, sell the product, pay for advertising it, and so on. In fact, a company can't exist unless it has the money to pay for all of the things you have mentioned above, including the fancy stores, employees, and so on.
Apple, just like other manufacturers can't exist without profit. That is a market reality. The only thing the company has to do is to continue expanding its customer base, all for the benefit of the shareholders. It means that it would meet the "base" specs of the product it designs, instead of exceeding the product specs with more rare or expensive materials. The latter requires a higher price as you can see in the "base" Macs versus the more powerful and expensive Macs that require copper heat sinks. In this case, copper handles heat dissipation better than aluminum.
If aluminum meets the design specs (tensile strength, etc.), then titanium and other expensive materials aren't needed. The same can be said for copper, stainless steel, aluminum, versus gold electrical contacts.
