Asians are a minority group, but are vastly over-represented in tech, to the point that even white people are under-represented by comparison.
The concern about racial diversity tends to focus on the idea that white hiring managers are subconsciously selective against non-white applicants. This doesn't make sense though when you factor in the minority groups that are actually over-represented.
So what has happened is that the argument has shifted to ignore Asian representation and only focus on black and Latino representation, while still coming to the same conclusion that white hiring managers are subconsciously racist and that the company needs to take corrective action.
The representation of Asians and Indians in tech should not necessarily reduce concerns for other minorities that are under-represented, but should definitely change the way those concerns are framed. The fact that it hasn't suggests that some sort of tomfoolery is afoot.
