It is nonsense. The gist of the GPL is "software must effectively come
with corresponding source code". Where "effectively" means either
distributing the corresponding source code right next or with the binary
(without extra cost), or the written offer etc (GPLv3 offers other
There is no obligation to "source code in all its versions", just
"corresponding versions", and there is no obligation towards anybody
except recipients of the software (though they may pass on an offer in
writing, more or less).
