The Open Source ideology is misused by companies: its ideology concerns production (similarly to FLOSS). You contribute to the software back.

Copyleft can force an absolute minimal “contribution” back to your project, but it can’t force a good-faith one. This makes it an inadequate tool towards building something with the kinds of values that many developers care about.

But I do think I’ve properly identified the problem: many developers conceive of software freedom as something larger than purely a license that kinds in on redistribution. This is the new frontier for those who are thinking about furthering the goals of the free software and open source movements. Our old tools are inadequate, and I’m not sure that the needed replacements work, or even exist.
