The House Committee interview in the last link (TechCrunch) shows that Zuckerberg does not like to use the "shadow profiles" term, but it's what others use to refer to Facebook's tracking of non-users.
I work there. If "shadow profile" means a profile that's created from PII for a specific person that doesn't have an account on the site, fb doesn't create shadow profiles.
Then how did FB display a lot of info about me, and recommended me all my contact list as friend recommendations when I created an account after not having one for 10+ years?
It's OK to wish to defend your company, but please do not lie; nobody forced you to comment here.
That you are that specific about P2 very clearly tells me that Facebook actually does create shadow profiles. I believe you that P2 isn't the basis of such profiles.
