Shouldn't this be if (!disabled)? If this is not the case, then variable names
are confusing

Um ,no. We add "disabled-by-default" categories to included list if it's ticked
in UI. We add normal categories to excluded list if it's not ticked in the UI.
So, if (disabled) here and if(!disabled) below.
