To be honest? I found Yegge's leaving-Google post to be one of his most underwhelming to date. Even if you don't agree, it's a bloody blog post on the internet. It's not calling people out. It's not advancing a cause. It's someone talking about changing jobs; it could as well be a personal journal entry.
Spending as much time on it as Kessler did seems like a waste of time. Spending as much time as Krubner did on a rebuttal to Kessler seems doubly so. It's the height of making mountains of molehills.
