It is authorization in all but class B.

So a VFR pilot can climb into Class A once he has flight following,
right?

The other classes don't require an authorization, so flight following
doesn't really provide authorization for anything.

No, wrong. You need a clearance into class B. Period.

That's not what I said. A controller who knowingly allows a pilot to
enter Class B without warning him could be considered negligent,
irrespective of any wrongdoing on the part of the pilot.
