True, it's not easy to do, and maybe it's not feasable to determine who is using the data. I don't know, maybe someone from Facebook will chime in on the issue, or leak some more info about company behavior.

>I think some caution is a good idea, they don't want to get the numbers wrong - although they are making steps in the right direction with the message to 87 million on their news feeds.

Totally agree with the second part, but ~4 years (only divulging the info when forced to during PR damage control mode) is well past being cautious. It's being cautious with the amount of damage the disclosure does to your profits, Equifax doesn't even wait that long.
