Curiosity
Do you realize that Apple's Mac sales and respective profit on the Mac department are higher than ever, right?
You do also realize that despite everything you said, Apple's pro apps revenue and profit is greater than ever too, right? (Asymco has a great article on it).
Clearly you can't please everybody, and choices had to be made. Apple's previous pro apps (Aperture, FCP 7, Logic, even iWork) had a lot of bloat and old code and had to be rebuild from nothing. 20 years of app development had to be disposed.
It will take time, but Apple has been going in a straight line, full gas, focusing on it. Some features will make a come back (they have too), but those apps as an whole became so much better! It's thanks to those decisions and the iOS ecosystem that the Mac has been growing so much, despite a world that was previously dominated by Microsoft.
Another way to look at it is the following: People have to learn how to learn. It's as simple as that. Those IT folks that are burying themselves in IE8 and refuse to look ahead, those that do the same with FCP 3 or 4, Adobe Photoshop cc 5 etc. and always complaining DO NOT MATTER for any company that looks to the future, especially in a world where more and more people are computer literate. So you either adapt, or perish. Apple's approach and decisions do not fit with your goals? Change to other software, then. But most of the people that are complaining do it because they are lazy and would complain anyway. If they are Windows users, they are still on XP or maybe 7. On the Mac, they are running SL. Who cares about them? No one, as the current landscape + revenue + profit + business health shows.
One thing where I have to agree is that instead of throwing away money to shareholders, Apple could invest even more on projects like these and make things much better. Adobe and Microsoft aren't worthy of being benchmarks to beat, anyway, and the good folks at Cupertino have an endless river of resources and talent.
However, based on their results (not money in itself, but the quality of their line up, offerings, etc.) how can you do not agree and admire their approach? Before the iPhone, in 2007, they sold less than 5 million Macs during the year and some millions iPods. They focussed on their OSes and Pro apps.
They grew so much since then! They had to focus, while starting from scratch on some areas (like cloud and data center infrastructure, services) to improve their products and compete with companies that were emperors of that space (Google, MS).
