> It sounds rather like customers get source access. Technically, you could provide binaries and a GPL license, then provide source code when verified customers (eg they send their receipt/license number with their request) ask for it. IANAL, but as far as I can tell, there's nothing in GPL that says you can't sell the software and operate this way. If your customers hand out the binaries to third parties, that's on them to provide the GPL and source code, not you. And of course, they could sell, re-release, etc, but anyone else could come and do the same to them. It's risky, to be sure, and it feels "wrong" only because we've become conditioned to the status quo of so-called "intellectual property". Frankly, I would love if I could write open source software for a living, but there's a big fear of letting go of a steady paycheck (and benefits!), but that has more to do with entrepreneurship fears than software licenses.
