It’s not really whataboutism. Would you take an environmentalist seriously if you found out that they drive a Hummer?
When people have choices and they choose the more harmful action, it hurts their credibility. If Rob cares so much about society and the environment, why did he work at a company that has horrendous track record on both? Someone of his level of talent certainly had choices, and he chose to contribute to the company that abandoned “don’t be evil” a long time ago.
Honestly, it seems like Rob Pike may have left Google around the same I did. (2021, 2022). Which was about when it became clear it was 100% down in the gutter without coming back.
I would argue that Google actually has had a comparitively good track record on the environment, I mean if you say (pre AI) Google does have a bad track record on the environment, then I wonder which ones do in your opinion. And while we can argue about the societal cost/benefit of other Google services and their use of ads to finance them, I would say there were very different to e.g Facebook with a documented effort to make their feed more addictive
