ELI5: why do people eat their steak bloody, but freak out when a burger still has red meat inside?

Most bacteria grow on the outside of steak and usually don't get in the center of the meat. With ground beef (burger) the surface area and places that bacteria can grow are very high. Additionally, ground beef is usually mixed up which allows for mixing off bacteria within the meat.
