I wonder if you've posted the derogatory statement if you were the author of F.lux. Have respect for free software, have respect for the time & effort of the coder, have respect for the people who care to share and if you can't "show" respect, at-least do not show disrespect. FYI, I (and many others)discover tons of cool work on HN everyday because they're reposted by someone who cared to share. No hard feelings. Peace.
