I may be wrong, but I think the crux of the matter is that 4e powers typically are used by the player to exercise some narrative control over what is happening while 3e activities were typically consciously 'used' by the character
The real 'dissociation' if you will is that for some players it seems quite natural for the activities to represent what they want to happen for the characters, while for other players it seems natural that a character has a range of capabilities which the character themselves 'could choose'.
( magic tends to be excluded from this issue because it is magic and thus limited use rules don't seem jarring in the same way that limited use of martial powers does)
