I don't doubt this sort of discrimination happens, but is there some sort of data to suggest this is more than isolated? I'm not Indian but rather Bangladeshi (the low-caste Indians who converted to Islam to get out of the caste system, lol). And I've met the occasional proud Brahmin, but in decades of living here I've never heard of caste discrimination being some sort of systemic thing. And yet I've seen like dozens of articles on this all of the sudden.
I'm not endorsing the idea of "isolated incidents" in general! But you can look at data to show that disparities in how certain groups are treated--e.g. employers being less willing to call back candidates with "Black" names on their resume. But extrapolating from the Cisco lawsuit to a narrative about a larger problem in Silicon Valley can have ugly consequences. It can be flipped around to broadly paint Indians who are in leadership positions in Silicon Valley in a bad light.
