Great point. it is how Facebook gathers almost global info from the web to feed their db and use with impunity. did Facebook record my id when I visited the page and tie the event to my Facebook user id? The answer is likely yes weather I have an active fb account or not. FB is a network, not a platform, that has turned into a massive surveillance and population mind control tool used by those who own and have influence over the network. For the sake of all users this must change. For the sake of the free internet.

These widgets are also how facebook is able to fingerprint and track people who don't have facebook accounts.
