Yeah, except for the fact that Google isn't blocking other search or ad providers on Android phones. The Google hate runs so deep that people like you simply resort to spreading lies. So sad.
Whoo there, let's not get personal. I'm not making personal attacks against you, and I don't expect to be called a liar unless you can point out were I'm factually wrong, and even then that would make me wrong not a liar.
Google blocks others services by forcing it's partners to bundle it's services if they want access to the google app marketplace and other high value assets of android that are closed source and owned by google. Sure anyone can take the base code from the open handset alliance, but without access to google value items then that manufacture would be at a distinct disadvantage. This is right out of MS anti completive playbook, MS never forbid it's partners from using other OSes they just made sure that if they did then they'd lose all the pricing advantages, or in google's term access to the app market and other services to disadvantage them.
