Why? Well, if you don't give them for free, every character (except Lazylords) will eventually take the Expertise feat, usually around the end of heroic tier. On the other hand, if you don't give them for free, many people won't bother ever picking up Improved Defenses, because it isn't all that impressive for many kinds of character.
If you take an average level-11 character, it'll have seven feats; almost universally, Expertise will be one of those; and also almost universally, Imp Defenses will not be, because there are many better feats.
And yet it is rated light blue to gold in paragon and up for virtually every class in the game, and is about universally agreed as necessary to have NADs keep pace with monster attack bonuses. While Heroic characters may well not take ID, most characters will take it at some point in Paragon. At the very least, it will be taken/retrained into by Epic (unless the Superior line is being pursued). Ultimately it is a feat nearly every build in the game will choose at some point. It tends not to be picked as early as 11 because there's usually a super high priority Paragon feat or two that must be taken ASAP (such as Lasting Frost or Spell Focus).
