Ask HN: Why aren't more people writing blogs while still employed @ FAANG?

I'm seeing quite a few sudden posts/blogs/tweets/etc., once the new round of firing is going on at Google. This time we seem to be dealing with people having been with the company for a min of 10/15+ years, which makes them direct participants in what they now so strongly criticize. Why aren't people starting documenting degradation while there may still be time to fix things?!?
