From what I understand, the "catch" (trade-off) is the "will distribute only free apps". As an example I would think that a University teacher would release his/her app with the classroom material thus free app, mainly for the students - no point charging as the whole effort is not a "for profit". Same for various orgs/NGOs who would need to reach out to provide news (e.g. United Nations). This for me (who pays the $99) is honorable and shows that apple does indeed separate the for-profit efforts from the non-profit efforts.
