Facebook is the only platform that lets advertisers target a mass audience with very fine demographic precision. Google you lose the demographics. Television, you lose the the precision.
All advertising platforms deliver fraudulent/worthless/imaginary/bogus views. Print has a problem with publishers making up circulation numbers. Television has a problem with ads running while no one is watching. Radio has a massive problem as their listener numbers have collapsed. The display ad exchanges have tremendous problems. Mobile apps have an incredible amount of accidental clicks which may often either be 10 year olds trying to play a game or just outright fake. Video ad networks have a problem with ads auto-playing on repeat that are seen and heard by no one.
Google and Facebook are about the easiest to deal with, by far.
