Google on the other hand fights strongly for a blogger's right to say whatever he feels like, even when it is arguably pretty nasty. They are like the ACLU in that respect. Google has the money and legal muscle to go up against law enforcement, private tort attorneys, judges, the feds, and the NSA. They are really aggressive in not folding and giving up your personal information when asked for. They put up a fight.
All in all, I'd go with Blogger over WordPress any day. If you want to do WordPress, buy a Dreamhost account. They will install WordPress for you and update it regularly for you. Don't host on WordPress.com.
