I was speaking only of unpaid volunteers.
I know. But those are only a subset of the contributors. And eg. for big, important projects, development is done mainly by companies (eg. Linux Kernel, Java, some GCC infrastructure, Mozilla, WebKit, etc), even if the commiters are listed individually. As I explained, the idea of the poor lonely guy in a basement writing code and being sued by the "big corps" is skewed from reality, and it has been for many many years.
The term quantify means to assign a number to something.
That number may be absolute (as you're implying with the SI reference) or relative. Checking yourself into a hospital because of an anxiety attack and getting a prescription and some off time because of the whole situation is easily quantifiable. Many health-related quantifications are done in percent of an expected, well known pattern. And insurance and disability funds are paid based on that.
I doubt that a few github takedowns are really going to impact a professional operation, however. They tend not to use sites like github as part of their core workflow. It mainly gets used by those poor nerds in basements.
While I do agree with your point (relying on a 3rd party is usually not a good idea, specially when you can self-host the codebases), this is more common than you think. I myself maintain/contribute to several private (paid) repositories that rely on external dependencies from OSS projects.
There is no criminal remedy to a false DMCA complaint that doesn't require a prosecutor to file.
Again, if someone publicly acuses you of a crime that is later proved you didn't commit, you are entitled to indemnification by damages caused to your reputation and your business/whatever. As this is not a matter of crime, it is a dispute filed on a civil court. There is no prosecuter on this. It is a dispute between two entities.
I'm really only concerned with the guys doing unpaid volunteer work here.
Yeah, but again, they are only a subset.
The community-driven project can't afford to deal with the likes of Qualcomm
Please tell me one well-known, widespread OSS project that is completely community-driven and mostly built with unpaid volunteer work. And no, stuff like foundations don't count - they're done for tax purposes.
