I was typing up a long reply basically saying this, but you summed it up. In most cases, it’s pure nonsense. Unless you’re actively sharing legitimate trade secrets that you were especially privy to, which could reasonably tank the company’s position or competitive advantage based on your actions, it’s trash talk. Change roles to your biggest competitor and tell your CEO/president to eat a side of juicy cockroaches alongside their breakfast of profits while your new employer values your particularly meaningful “suggestions”.
Wow thanks for sharing that gist! I never even considered installing and don’t use it, it’s just wild to see how insane that list is.
