If you look at the bugs in the article, they're not that foolish. They're basically perfectly valid things to be able to do: entering text in a text field, or pressing buttons to do things. There is a specific set of valid input for your gas tank, but anything that is text should be accepted for text input.

The analogy would be something like that:

- if I throw spaghetti on my windshield, my car shouldn't break down

- if I hold the wiper's stick to the position that runs it once (instead of putting it in the position to continually run) my car shouldn't break down
