I disagree. Pulling access to something you've come to depend on (especially, derive your livelihood from) is worse than never fostering that dependence in the first place.
I was aiming more at the idea that it would be out of character for Apple to completely restrict access to just certain sources of apps. If we're talking about whether Apple would take something away that people had come to rely upon, well, there's a whole long list of technologies I could list off to support the idea that they have no problem doing that....
