Irregardless of your extremely poor attitude, I shall point out the obvious: 'ProcessBlue' himself has stated in capital letters that it is free. I was just correcting that.
Everybody knows what "free" means in that context, so your "correcting" is not actually adding anything to the conversation. Perhaps you think you are informing people, but everyone who reads your comment already knows what you're saying, so it's not informative at all.
