Five years ago, I paid a flat $45 fee for Cold Turkey, software which does the same thing on Windows and Mac which doesn't require I chip in for no additional work on the developer's part; It is completed software that runs on my own machine, just like Kiki.

Sure, diming $30/year is a 'better deal' than nickeling $5/month, but this is not the sort of 'deal' which this software warrants. This is not a service product, and pricing it like one is silly.
