I am not sure really. Actual extreme right wing parties are close to non existant in Switzerland, mostly because there is a big populist right wing party that got the nationalists/xenophobes covered and since they are terrible but also not total idiots, they know better than to badmouth the national team!
I'll assume they don't care when the team wins and blame the albanians when it loses! Note that all the players are either born in Switzerland or immigrated when 5 or under (with the possible exception of Embolo, but he played for the youth national teams growing up).
From a sport standpoint, they are all players who learned to play in Switzerland, which should be the criteria for selection really, more than the passport.
