My 3 cents

:
1.
I believe you've been lucky with your Fords, especially with the recent Ford Focus. The statistics on that car (especially the first years models) tell it otherwise (unfortunately)
2.
I think it has to do with what you have had. Reality is that Ford quality and design have been degrading over time. In the family we have owned several Fords as well:
Awesome cars
1970(?) and 1974(?) Ford Mavericks. Best cars. My dad still talks about them every time he can. Fast, fun to drive and ride plus both stick shift (Stick knob looked like a billiard ball)
Very good cars
1980 Ford Fairmont and 1985 Ford Carry-All (similar concept to a Chevy Suburban, very few made). I had a lot of fun with them and never gave me a problem whatsoever. 8 cyl Gas Guzzlers though. I learned how to drive in the Fairmont, so good memories as well...
OK car
1987 Ford Tempo GS. Oh well, did its job (mom's car) but was soooo slow and not very appealing...
Terrible car
1989 Ford Tempo GLX (top notch trim, bought brand new). Our last Ford. Man, that thing was better looking if you want, but if it was not the air conditioning breaking one day, it was an auto tranny oil pond in the garage, a broken window elevator or the electric antenna stuck in the middle of the way, just out of the blue (yeah with the recommended lub). It spent more time at the workshop than any other car I ever had.
After that, Mazda was my first purchase within the Ford "family" and happy with it so far... Maybe things have changed back for good in some aspects but...
