The tarball _is_ the "complete corresponding source code."

The git commit history is _not_.

End of story.

The tarball is not, these days, the source code in the form preferred for making modifications. If you have:

1. A git repo, that you and your organisation use for working on

2. A tarball made from 1 with git archive

And you try tell me that the /latter/ is the preferred form for you or anyone else, then I say you are simply lying (possibly cause your business model depends on it).

I'm going to take the FSF's word over yours.

Or are you accusing the FSF of violating their own licenses, possibly because "their business model" depends on it?

If you have a reference to somewhere where the FSF defines source code as something different to the "preferred form of the work for modifications", I'd be interested to read that. Regardless, the term "source code" is explicitly defined in that way in the GPL text itself - if there's some pronouncement on some obscure web page somewhere, that probably doesn't matter.

Further, again, it's explicitly defined in a way that allows the meaning to be context (including temporal) specific.

I can comply with your interpretation by supplying at tarball that contains a git repo with a single commit -- The complete corresponding source code to the binary I'm distributing. I am under no obligation to supply the source code to binaries I did not distribute, nor am I under any obligation to distribute any/all prior versions of the source code. [1] [2]

...Or are you arguing that everyone should be forced to publish every private intermediate draft or edit, even if there was no external distribution of anything (binaries or source)? Is git squashing and rebasing now verboten?

[1] I make a minor change to Linux to support my hardware. Should I also have to distribute all 3GB of Linux's upstream git history? What about upstream's pre-git history all the way back to 1991? If the answer is different, why,? What's the cutoff? one version? Five versions? One year of history? five years of history? What if I don't use *your* preferred VCS at all? Can I comply by supplying a SoS, Perforce, or Bitkeeper repository (that you may not be able to legally access because you worked on a competing VCS in violation of the Bitkeeper license)?
[2] Overly pedantic folks can argue that one needs to include "prominent notices" saying the date of your modifications (GPLv3 5(a) ) -- But you don't have to enumerate your specific changes, and the "date" can just be when you publicly published them in the modified work. Still, you can achieve both by your tarball'd git repo having two commits; the first being the unmodified upstream source code, and the second containing all of your changes.
