The current CTO of a publicly traded company had my entire engineering team rewrite an <anonymized internal tool>. Mind you, the current generation of the <anonymized internal tool> is completely fine, and in fact a massive improvement from our 1st and 2nd gen version. About a year into that completely useless project, the CTO lays off 2/3 of the team (including the original authors), reorgs another team into our team, and the latest gen <anonymized internal tool> is a complete pile of trash. I left the team a few months ago when I realized it wasn't worth the head ache of dealing with the terrible CTO, the literal human centipede which is the leadership chain, and the sales bro turned product manager.
