>You think Rob Pike was super happy about it?

He sure was happy enough to work for them (when he could work anywhere else) for nearly two decades. A one line apology doesn't delete his time at Google. The rant also seems to be directed mostly if not exclusively towards GenAI not Google. He even seems happy enough to use Gmail when he doesn't have to.

You can have an opinion and other people are allowed to have one about you. Goes both ways.
