First words of the post: «If certain people cannot contribute to the Linux kernel because of a list». Issue is raised against the specifics (validity, effectiveness, sense) of possible sanctions. John parks his car blocking your gate. Sanction A: you paint his car mauve. Sanction B: John's cousin is forbidden providing voluntary work. Sanction A and B are very different and some raise debate more than others. (If you want a more "actual" example - though besides official governmental actions - there have been pressing debates whether athletes holding some passport can can compete in international games.)
