Most people would expect a VPN to protect their data from websites, rather than sharing it with Facebook.
Also, Onavo was acquired by FB in 2013. What were you expecting FB to do with it? It is not even the most popular VPN app.
I presented factual and new information about what data is collected and asked some questions.
Instead, from what it appears, you were trying to prop up views by calling out a facebook specific vpn and how it collected all data - as in you were expecting that to behave differently.
I never claimed they are collecting all data sent and recieved from the device, nor would I have any ability to credibly make that claim without access to their servers. I only addressed what is observable in the app’s code.
