What you're talking about has been a long time in the making. It's been a slow, predictable process, since the Jobs era. It hasn't come out of nowhere.
Regardless; what you're upset about isn't going to get any better for you. It's not going to go back the other way. Apple will only cause you more pain from here. That much I can guarantee. So best leave now.
I pretty much already have; ditched my Mac Pro and built a hackintosh (runs circles around any desktop mac, its not even close). I ditched the iPod a long time ago (way before it's demise), didnt bother with iPhone and am selling my MacBook Pro. Apple's not getting another dime out of me. Greedy morons have disrespected their consumers for long enough. This sh*t needs to end.
