Popular dictionaries (Webster/Oxford) don't include national origin
The usage of the word "racism" to include xenophobia is common enough in a casual context that I cannot believe that you are simply not aware of that usage. By choosing to argue over the semantics of the word racism over usage you probably already are familiar with, you are diverting attention from what really matters here: that said racism or xenophobia exists and negatively affects real human beings.
(Not that any xenophobia is particularly better than any other, but it’s difficult to talk to people when they use broader meanings for words you thought meant very specific thing. See also terrorism vs insurgency, genocide vs occupation, etc.)
If anything, attempts to redefine racism as only American variant where it is all about shades of color is redefinition.
And obviously, ethnicity and geography goes with races.
- Even if you use the broader definition to include nationality, in this case, the "hackers" are physically located in the geopolitical boundaries of India
- Nearly every major country with a large enough population has people in whitehat/blackhat infosec professions. It is an incredible reach to suggest that newspapers should not identify the national origin of these individuals because of what some racist readers might start to believe or become biased towards, by drawing non-existent lines to patterns that don't exist except in their own bubbles. Editorial standards and responsibility should not be driven by the weakest minds.
