No discrimination by political opinion is not practically possible.

The added problem here is that whether or not xsnow counts as "protestware" depends on your point of view. The thing that makes it "protestware" is that it displays a certain symbol, and if you're in a specific subset of locales, it displays that symbol much more frequently than if you're not.

It doesn't ban you from using or modifying it (you could, quite legally, replace extratree.xpm with something else, for example), unlike your example of a program not to be used by South African police. As a result, it's not really "protestware" in the same sense as your second example, because a Russian could easily have a package to replace extratree.xpm with (say) a drawing of a larch (or other tree). Further, once we have world peace, and flags stop upsetting people, the xsnow "protest" becomes a non-issue; it's only an issue because of current political views in the Russian Federation.
