FB change makes it hard for campaigns

New York

WHEN you log in to a politician's Facebook app, the campaign enjoys relatively easy access to your friends on the social network. But starting next year, that automatic access will go away.

That may provide users with some relief from unwanted messages. It will certainly help Facebook respond to complaints that it shares too much of its users' information without their consent. But it also could lead to more campaigns advertising on the platform, which is good for the company's bottom line.
