No you are minunderstanding the GPL.
You are only required to provide source to those who got the binary
artifact(s). They then have the full GPL rights to further modify etc.
In many cases the binaries are distributed to everyone and then so is
the source. In other cases (such as RHEL) only source is provided to
everyone (but that is fine too).
Consider a simpler case: I make a copy of a existing GPL pkg. I modify
this and use it myself. I do not have to share my changes with anyone.
My copy is still GPL though..
..so if I give a copy of the source to a friend it no longer matters
(to him/her) wether I made that source public before or not. They can
modify or not and make available publicly or not.
Had I sent my friend a binary copy he/she would have had the right to
require me to also hand over the source.
None of us would have any obligations to a 3rd party.
