wolfsite: Those other sites offer official install packages for Windows/Mac/ and Linux so they have people that can offer support for all of those packages. GOG only has the Windows installer and more than likely do not have anyone on staff that can help people on Linux if they have a problem.
lenny3: "Those other sites" (which is almost entire Internet which do it in normal no-nonsense way!) allow you to download their software from Android phone or whatever other device, they don't deliberately block download options if you happen to access their page from other device. Do you see the difference?
Galaxy only has one version, this part goes into speculation but they may feel they don't want to have the link available to cut down on support tickets for a problem they will be unable to offer assistance to since they do not officially support Linux.
Another reason could be to avoid negative press if people download the program on another OS but don't understand that it was not made to function on that OS then those people spread word that the program doesn't function at all despite not realizing it was not made for the application (this is a possibility as there are more people coming to use other operating systems that are not familiar with executable packages usage and OS limitations.
Again I can only speculate on the reason but in the end it is there software and they do have the right to make it available, or UN-available in any way they see fit. You may not be happy with it but that is what they choose to do.
