iNS is an app that was created by a few very dedicated individuals who wanted to see an app get created. They have poured a lot of time and effort (which if you have the slightest idea of how the real world works, time is equal to money, however, this thread makes me think that you do not have much of an idea how the real world works) into creating an app. These individuals are not admins for NS and are certainly not getting rich off creating iNS.
Secondly, you are not required to purchase iNS to use Newschoolers.com. Noone is forcing you to purchase the app. It is nothing different than a t-shirt, lanyard, or sticker pack in the store; if you like it and have a use for it, you may buy it. If you do not wish to buy it, then you aren't obligated to purchase it.
If you feel that $1.99 is too much for iNS, then that is your opinion, and feel free to either create your own Application for a mobile NS, or continue to use Safari to access the site on the go.
