Someone decided to handle this situation that way, so one has a perfect right to be angry at them, and generalize that as "being angry at Google".
The author takes it with philosophy and pragmatism, that's admirable and I'm certainly not one to tell them how they should feel. But other factors indicate that his situation was also prone for that positiveness (feeling like a relief because of golden handcuffs, long tenure in a stock-distributing tech company + director level meaning that there's likely no concerns regarding money, side career already underway, maybe a relief to have some change).
Others might not be in the same situation, and are now jobless in in slow economy, with tenuous savings, rent or mortgage coming up. They might feel outright furious for a layoff that they have neither control on, nor were a reason for, and that shows no face to take responsibility - and they're completely entitled to feel that way, if that helps them cope. I'd say it makes sense to me, and don't feel bad for being angry if that's how you feel.
