It is exactly that and it’s clear the author is one of these “yappers”. I like that term. These people are also absolutely obnoxious irl and completely fail to read the room. I once had a PM like this who went into a near mental health crisis that the team of engineers were not “engaging” enough with her (in her head) witty “engineer” banter.

Perhaps it’s useful to have these people in the office, in a room of mirrors, where they can listen to themselves talk all day. There’s a subset of people who have weaseled their way into tech coming from the world of hyper-anxious very public social media engagement that simply make life miserable for everyone else.
