I understand why somebody would be scared of that. They're big and important to the tune of many many billions of dollars, while you or I are not. But you shouldn't let that get to you. You should make a conscious effort to not let that get to you. If they want you to take their problems personally, let them hire you. If they can be broken by you but are unwilling to pay you, then fuck them. Put them lower in your priority queue than private individuals.
