I love that open source exists and am very grateful that people have given their time to make stuff that I get so much pleasure out of using for free. I feel like the article suggests that programmers are the only people who ever produce work on a voluntary basis though. "If you ask an engineer, a doctor, a professor, a teacher or a farmer to give you one of the products they do for free, probably they will just refuse. You won’t find a professor working full time in a university for free. You won’t find a civil engineer working on building houses for free. You won’t find a farmer giving you vegetables for free." If you ask Adobe to give you Photoshop or someone who makes a piece of $10 software to give it to you for free they will probably refuse. There's a difference between offering something voluntarily and offering something for sale then being asked to provide it for free. Engineers do sometimes work for free eg. on charity projects as do many other types of business. Even ad agencies I've worked at did a certain number of free projects for charity. A farmer does regularly give me vegetables for free. I've made software for free but I've also spent a lot of time making props, art and other things for free. A friend runs a small charity, she works long full-time hours unpaid and often has trouble getting her own bills paid. I've also known more than a few selfish coders... I'm certainly not arguing against the premise of being thankful for free software (thank you programmers - I really mean that, I've sent messages of gratitude to devs in the past and am reminding myself to do it more in future) but let's not start thinking that software developers are inherently better human beings than anyone else. Feels a bit myopic :)
