I decided to pay the $7
Well, I don't like to pay for things that I think should have been included with OS X. But you know what? I'd rather for over $7 for the software to a small company like Unsanity that needs every dollar it gets rather than some gigantic corporation. Besides, if you think about it on a per/monthly usage, I've paid less than 60 cents to use the program if I plan on using it for a year.
I think that's a fair price.
