Having worked in politics, where Hanlon's Razor is often used to excuse malice, I'd suggest it is not valid. People have reasons for acting incompetently - often those reasons are because the system is set up to enable that, in one way or another. And it's most often the case that system has been set up intentionally in that way (or has been manipulated to get that outcome) - there's malice in the organisational big picture. The effect is the same and the cause is the same as well.
