Do you think U2 has a lot of rip off songs?

Angel of Harlem sounds like Bob Dylan's like a Rolling Stone, Vertigo riff sounds like Whole Lotta Love, the name Sunday Bloody Sunday, its kind of too close to Sabbath Bloody Sabbath, Vertigo vocals sound like No Man's Land by Billy Joel in places. They're so obvious though they don't even cover it in some songs like Angel of Harlem, how do they get away with it?
