Earlier quoted context omitted.
>The reason is that the adjective ruskie is typically understood as "Russian" in general parlance I’m not a native speaker, but I always heard that the Greek derived Rosyjski/Rosjanin/Rosjanka were for Russians (ie the ethnic majority in the Russian Federation) but Ruskie was still reserved for the Rus’ in general. I’ve had native speaking members explain the distinction to me, that ruskie is more of a catch-all term…
"Ruskie" vs "Rosyjskie" is a difference between common speech and more proper grammar, but in regular usage of the language they both mean the adjective "Russian". I'm native.
Is there a tendency to group them together? As Russians or as Rus’?
There is a lot of cultural context that Western Europeans (inc myself) are not aware of.
