I am saying that Devuan developers feed patches upstream to the original app/package developers
Ah, OK, I'm just in the habit of thinking of Debian as the upstream for Devuan, after all Devuan ASCII (main) contains 75579 packages, and all but 789 of them are identical to the Debian Stretch packages. (In fact the packages that are the same are physically stored on the Debian servers).
Go to the Devuan forum and ask the horse's mouth for yourself: https://dev1galaxy.orgI'm reluctant to do that as Jaromil thinks I'm "agressive".
(He was making wild accusations against the DPL, I showed him his claims were wrong and mildly told him that crying wolf was maybe not a good idea, so he said something on the lines of being proud to be a wolf, so I sent him a link to some music by Sergei Prokofiev and he banned me for being "agressive").
