Petition the anti-tabbing scam?

The tabs found on mysongbook, powertab, mxtabs etc are the listener's interpretation of the song very much equivalent to a song review. It is in no way plagiarism. If artists would make their song books available in the form of guitarpro, powertab or something smiliar, I might buy it. I dont download such tabs because I dont want to pay the artist, but rather because what the artist provides me doesnt suit my need as best as something I ironically get free.
