I don't understand the point of that.
Users who know Facebook will trace all their actions using VPN still gonna use it? Ridiculous.
"To better track what users are doing outside Facebook, the company created a volunteer program called the “Facebook Research App” that functioned as a VPN when installed on phones. The VPN sent data to Facebook, including websites visited, messages sent, photos, videos, and more. The app also required users to install a root certificate, which allowed tracking data that would typically be encrypted. Volunteers had to choose to install the app, and received $20 a month in e-gift cards."
This security breach unearths an ugly truth that all VPNs may not be what they appear to be. I'm sure you noticed folk flock to install a VPN in search of privacy but then there's this showing it can also be a way to collect what you thought was your private data.
Another knock for those Free VPNs?
