The context is that a partial descendant of an enemy species (Romulans) was the victim of a witch hunt. He was half human and a starfleet officer. He had lived in the federation his whole life.
A real world equivalent example to that would be banning Americans with Russian ancestry that were born in America and lived in America their whole lives from contributing.
That is not what's happening here. You are arguing in bad faith. Picard would be perfectly fine with preventing Romulans in the Romulan Empire from accessing/modifying sensitive technology.
How does this prevent the Russians from accessing sensitive technology? Oh it doesn't! It just excludes them from contributing to Linux, not from using it.
Accusing others from "arguing in bad faith" are we?
