Never ascribe to malice that which is adequately explained by incompetence. Never ascribe to incompetence that which has been explained (and corrected) simply and yet continues to persist.
When incompetence becomes willful then it is, indeed, malicious.
No matter how willful you are with your incompetence, when you choose an action, you choose the consequences of that action. And when you desire a consequence you better take the action that will create it.
Put another way, if you know what to do you and you do (or don’t do) it, there you bloody well are, aren’t you?
