honeypot is an enticing … thing that you use to gain an advantage over someone. I’m implying the facebook open source stuff is bait and they harvest something from you, be it data, legitimacy or something else.
Unless you have some evidence to say otherwise the open source projects don’t report back to Facebook servers so they don’t collect data on anyone.
It’s hosted on GitHub so if anything it collects data for Microsoft, and knowing Microsoft they don’t do anything coherent with the data.
