OP's blog post also rang false to me. It feels like it was written by someone who works in HR trying to promote a culture that inhibits real interactions, under the guise of being "a good human being."

Being a good human involves honesty and naming things that are extremely difficult to name when you're both employed at the same place. I've had so many honest and illuminating conversations with coworkers after one or both of us left a company or organization, conversations that deepened into real friendships instead of just being colleagues.
