I spend more time in the web browser of computing devices than anything else. I don't think I'm unusual
You are unusual if you are talking about a smartphone. If people have a choice between an app and a website, they choose the app -- at the very least, it involves one less tap. Remember when we used to talk about having fewer clicks, and complained about websites that required two or three more clicks to get to the things we wanted?
corporations are just a bunch of people
A bunch of people whose operations are done using money borrowed from other people who want to see a return on their investment. A corporation cannot let values or anything other than a nation's laws supersede its profit motive without the consent of its investors, and it is naive to think that Apple's investors care about anything other than the return on their investment.
Let's put it this way: Steve Jobs admitted that the tantalum used in iPhones probably could be traced to Congo, where teenage soldiers are being ordered to rape women as a military tactic in a conflict that is fueled by minerals. Did Apple take some grand moral stance and spend money on either ending the conflict or finding alternative materials? No, Apple simply said that tantalum is needed to make iPhones and that they could not do anything about the conflict (despite being a corporation with enough capital that it could buy the entire region).
the complex reality and explanatory power of other motivations and causes
I call BS on that one. The only complication is in how corporations choose and exploit their markets, not in the purpose of their existence or of their ultimate goal. Apple is not creating computers out the goodness of their hearts. Apple did not sue journalists out of some moral obligation. Apple did not go after hackintosh makers for any sort of greater good. When Apple gives to charity, do they do so quietly, or do them make sure lots of cameras are around so that everyone knows about their service to the world (when/if you give to charity, do you then go around telling everyone about it?)?
It is kind of like saying that there is a complex reality to an army at war. Sure, different armies do things differently, and they are fighting for different reasons, but at the end of the day an army has a goal when it fights and that goal takes priority. Corporations are not all that different from a military operation: the people who work for them are trained to think they are doing something important, they are trained to think that they have an ethical obligation to follow orders, and at the top level there are people who direct operations to achieve the goal.
Apple and other technology companies that have been hugely shaped by one person
Apple was led to an overwhelming success by one ruthless person. Steve Jobs was not on some moral or ethical quest; he wanted to lead Apple to a great business success, and was willing to do whatever it took to make that happen. He berated employees if they were not perfect. He directed the company to patent everything, so that they could never be sued without having some counter-suit ready. He directed the company to go after anyone who stood in the way of the company's profits. It is as if he read Ender's Game and thought, "I bet Apple would be the most successful company in human history if someone like Ender Wiggin were to run it..."
Which of Apple's or Jobs' actions leads you to think otherwise? Frankly, which of the technology companies that was driven to success by one person suggests a different story? Facebook has yet to work on any sort of interoperability with any other system, and is increasingly aggressive about profiting from its userbase. Google does not stop short of doing business in countries where they are required to be evil. Oracle is as typical of a corporation as possible. Do I even need to mention Microsoft?
