"Never attribute to malice that which can be adequately explained by stupidity." - I really doubt they planned on designing crappy DRM so that they can remove it and gain the good will of the fans.
I think it's much more likely a bunch of execs thinking they can do whatever they want and "those desperate suckers will buy it anyway".
This *IS* EA... the company that plans to start selling game demo's calling them "Pre-Downloadable Content" couldn't it be malicious stupidity? maybe stupid malice? Dont forget the rest of that quote you are using " Never attribute to malice that which can be adequately explained by stupidity, but don't rule out malice." The PR arm of a mega-corperation can often be perfectly happy being both mean and dumb in equal parts.
