All the fired xooglers seemed to praise their former employeer on social media, so they seem to accept that they deserved to be fired. It's hard to be mad at the CEO, when the people who lost their jobs displayed no anger.
Consider the selection bias of people posting on social media. Also consider people would want to be positive on social media to keep their future employment prospects.
If they were mad about it, they would have posted, wouldn't they? Silence is violence and all that.
If anything, it is easy to see an incentive not to post negative things online, as you can see on LinkedIn everyday.
