Comment Lots of projects are work spinoffs (Score 1) 301
Several of the projects I've released were written in-house for my employer to accomplish a certain task. Because I've made it a habit to work for enlightened employers, most of them have been receptive to me releasing my non-company-mission directed software under various open source licenses.
So say I'm working at Foo Corp and wrote Bar Widget to help them get something done. Bar Widget isn't something we make money directly from. It's just a piece of infrastructure that we needed, and my boss is cool and lets me put it on GitHub. You come along and say, "hey, JSG, we'll give you money for Bar Widget as long as you send us an invoice for it." Great. Thanks! But how do I do that? My boss is a good guy, but asking him to let me send companies invoices to use the software he paid my salary to write is a bridge too far. So maybe I ask Foo Corp to bill you instead; then what? I'm only going to see a portion of that money, probably routed in as a (taxable!) bonus on my next paycheck, minus however much he thinks it cost him to process the invoice, accounts receivable, etc.
In that situation, I'd have given you a heartfelt "thanks for thinking of me!" and started ignoring your calls and emails, too. It's not that I don't like free money, but that I don't actually have a way to accept it that won't either 1) get me fired or 2) have such a high overhead that it's not worth the effort to collect.
