Well, and also the fact that the contract appeared to be unfair and skewed towards Google, but it is not widely discussed (perhaps because Google wants these contracts to be secret)
1 - given the impact on the music industry, I don't think Google has any business insisting they remain secret, and I rather like the irony of something leaking that Google wants to keep secret.
2 - it has already been reported by some artists (in public) what Google was trying to get into contract, I think some Indie labels as well as an independent artist have given chapter and verse about it.
Personally, I think this ought to have sounded a very loud monopoly abuse alert à la Microsoft, but it appears Google manage to encourage the relevant regulators to look the other way.
