Actually taking and distributing pictures of the earth from space requires a license (issued by NOAA of all agencies) which requires certain protections for the national security of the US and some allied nations. I presume the other nations capable of launching satellites have similar laws in place. SpaceX had to modify their launch broadcasts to stop showing images taken from space as they do not (or at least didn't at the time) have such a license.
