The Lock Screen displays what you ask it to. When you mark a phone as Lost or perform a Remote Erase, you can push down your contact data if you'd like (ie - if you think a "friendly" found the phone and you want it back), or you can elect to type nothing, an offensive message, etc. Likewise for the "Medical ID" feature (which is also available with the phone locked) - you can elect to display lots of details, some details, or no details at all.
