You can wish Microsoft would die, and still use an iPhone.
In fact, much of Apple's success can be attributed to Microsoft fumbling the mobile revolution. In other words, people who use Apple may be doing so directly because of how much worse Microsoft was -- due to Microsoft spending their limited resources on zero-sum tactics like shafting their developer ecosystem.
Compete or die. (Microsoft seems to act like they have a third alternative, monopolize. They're still immensely profitable so it's understandable that their shareholders are comfortable with their current course.)
I personally don't use any iThings. y4mi, do you have concrete examples of what Microsoft has done that has significantly improved end users' ability to run Free Software?
