It was not the pro users who made Apple rich. It was the consumers buying iPods, and later iPhones.

Pro users are at the same time extremely demanding and extremely conservative. Apple has never done much to cater to that market, and the fact that they have so many pro users these days is a happy accident which has more to do with how awful these people used to be treated when they were Windows users, and not a lot to do with anything Apple did specifically for their sake.

Apple doesn't care about pro users, whom they rightly consider demanding and ungrateful. Apple cares about ordinary people, the ones lots of pro users talk about often in the most condescending of manners. Apple's mission has always been to make computing accessible to the masses (remember the slogan: "The computer for the rest of us"?), not to make it better for the elite few who already know how to use one.
