Since Facebook introduced its Beacon program earlier this month, the
data sharing initiative has met with mounting opposition from users,
55,000 of whom have joined a MoveOn group protesting the initiative.
In response, Facebook has now changed the way the program is set up
to give users more control over which of their online activities are
visible to their friends. The new approach somewhat reduces Beacon’s
potency for Facebook partners like Fandango, Overstock.com and eBay,
which in theory will experience fewer referral-based visits. But it
preserves the essential structure of the program.
