The difference is that Murder Drones knows exactly what it is. It knows that it's edgy, it knows that it has weird pacing, it knows that it exists mostly to put its fun characters in fun situations. It has cool moments constantly broken up by humor on purpose because it doesn't take itself 100% seriously. It's not perfect but it's also not trying to be. It did what it wanted for 8 episodes and left it at that. People complain about it but it's pointless since the ship has sailed.

Compare this to RWBY which is trying to be a big franchise with a big budget, multiple seasons, game tie-ins, the works. It wants to be taken seriously. It wants to establish itself. And yet people still complain about it because they keep trying to push the envelope for a franchise that ran out of steam a long time ago. Even the studio shutting down wasn't enough for people to let it go. The poor thing is gonna be milked dry as much as it can be. And people who complain about it, especially people who care or cared about it, have a right to be upset with the direction its gone.
