He's talking about people who BLINDLY hate. People who talk shit for the sake thereof, who don't like apple so they don't like the iPad.
There's also a segment who'll fall in line with what they think is cool. It's cool to crack jokes about the iPad and their users, so they talk shit. If it were the reverse they'd be singing a different song.
He's not talking about the people who just prefer something else, like you.
