The contrast with Facebook couldn't be more stark.

Google is advertising the change extensively, and they explain it in simple English.

Google lets you opt out.

And if you were already opted out, they retain that more restrictive setting without you having to do anything.

I personally don't want to be an unpaid shill for anybody, which is why I refuse to create G+ or Facebook accounts.

But I have to recognize that Google's approach is far more open and honest than Facebook's.
