Is it possible that companies, teams within companies, and/or individuals might exploit "Hanlon's Razor" to their own benefit? It's easy to say "Oh, whoops" and often there's no easy way to prove incompetence vs malice. And because people are aware of this cliche/meme, they may be more susceptible to it.
I wonder if people said "Hanlon's Razor" when they first heard about the VW emissions scandal.
NOTE: I'm just thinking out loud here. I don't have any particular bias against Microsoft.
Maybe it's not wise to automatically assume malice if incompetence could be a factor, but it's also not correct to rule out malice just because incompetence is a possible explanation.
