What I am asking is: can other people create work / obligations for me to respond to written requests to package up and send some physical media (and collect a reasonable fee, etc.) for the source code of my GPL programs because they have been distributing them without the source even though in my original and current distros I include the source in the downloaded folder that contains the binaries (but in their distro, which could be a much more popular source of download than mine, they don't include the source)?
[For avoidance of confusion, I am referring to others distributing my GPL binaries without alterations and without them creating derivative works. Also, I am not referring to the use of any specific download sites like GitHub. This could be on any sites: mine vs. theirs].
