There are tons of things posted to HN, which inevitably some people find interesting and some people don't. The fact is, many H-1B visa beneficiaries are in the technology field.

Your stance could be taken on any technology-related content posted to HN. "Those who care about Linux will keep their eyes and ears open to Linux news. It doesn't have to be posted here because most OS users have Windows" sounds pretty ridiculous to me.
