Just generally speaking, I can't comprehend how people object so much about pricing.  There is an offer on the table, if you don't like it step away and keep it moving.  CS is absolutely entitled to charge whatever they want for their work, and you are entitled to either buy it or move along.  They were absolutely open with their plans to charge for the upgrade many months before they released it, how can anyone be surprised about it?

At the end of the day it is THEIR work.  If you want to design a project and give it away for free, let us all know.  If not, keep it moving.
