It's weird that the landing page has "Joe" and "Leo" (uncommon names in India), as placeholder users, but the authors are from India.
When you're writing English it just feels like the names flow better, that's all (like, avoiding stutter in a sentence, but with names). I don't think it would be fair to say we're just not honoring our roots
Also you could use "Joe" and "Pedro" instead. To me it seems even more global.
