I've had the same thoughts through this ordeal. If it's such a burden go ahead and stop being a mod. There's plenty of users that would gladly take your place. Yet I've not heard of any doing so.
Letting Victoria go probably sucks since she helped coordinate so much. But that kind of chaos or disorganization happens in any company I've worked for when a key employee is let go. Large corporations with paid employees don't always get this right. So to me Reddit's actions were no surprise, once the decision is made the employee is notified and shown the door.
Most companies will make plans to deal with associated problems, though, particularly when the company dictates the timing. I would expect problems if an employee suddenly quit without notice or became somehow incapacitated, but reddit seems to have made no effort to cover her job. It's as if they didn't realize what she was doing.
