I disagree. I am capable of writing a good commit message, I just don’t really want to. Depending on the change, formulating a concise text that includes all relevant information can be quite time consuming.
I can travel to Italy on foot. Will I do that? Of course not. What does it imply? That I’m incapable of moving my body? Of course not! It just means I’m too lazy to do it and that there are faster ways to get to the same goal.
