Fair enough. Yeah, I never thought of open and closed source as two exclusive options, but two of many.
I myself publish an application which isn't open source, but I publish the source code, as I believe my users have the right to know what runs on their computer, and have the freedom to audit, modify, and compile their own builds if they so wish. But I don't want someone to take and resell my application. I have yet to encounter someone calling my app closed source, but I can see how someone could.
Yeah, the environmental issues that are orders of magnitude less problematic than literally pumping the toxic chemicals into the atmosphere like with fossil fuels, vs comparatively miniscule amount of solid waste to store inert.
