It seems you do care, since you've commented twice now claiming the author has ripped off your work, without any evidence whatsoever. Perhaps you should contact them privately if you feel that you've been wronged here?

If a problem can be summarized in a few simple steps, then how different do you expect any posts about the topic to be?
