I don't know firsthand that Wolfram said something like

I think WRI have said that this is a Mac problem due to the apple
implementation of postscript/PDF.

However, they did report to me that a similar problem under Linux is an 
X11 problem. As I have before, I note here that we are buying 
Mathematica to do a job, not to be told that it is X11's fault or Mac's 
ps/pdf implementation fault. All that may in fact be true; however, if 
Mathematica doesn't work properly then it is broken and there is a bug. 
The sort of comments I have heard are really irritating, and I wish the 
developers would just accept the responsibility for a bad choice on 
their part, and then fix it. This rotated-text problem has been with us 
for at least two years. I second the thought that new features are fine, 
but how about putting a similar effort into fixing the old problems.
