I have mentioned a few times that Facebook cannot be trusted and that is the main reason why I suspended my account a few months ago. I am not impressed with Google either and switched to Qwant for my search engine.
An article in TechCrunch (see extract below) confirms everything. So now you have confirmation, Facebook and Google syphon all your data from your phone, tablet, computer and of course they sell most of it.
“The app, known simply as “Research,” allowed Facebook unparalleled access to all of the data flowing out of a device. This included access to some of the users’ most sensitive network data. Facebook paid users — including teenagers — $20 per month to install the app. But it wasn’t clear exactly what kind of data was being vacuumed up, or for what reason.
It turns out that the app was a repackaged app that was effectively banned from Apple’s App Store last year for collecting too much data on users.
Apple was angry that Facebook was misusing its special-issue enterprise certificates to push an app it already banned, and revoked it — rendering the app unable to open. But Facebook was using that same certificate to sign its other employee-only apps, effectively knocking them offline until Apple re-issued the certificate.
Then, it turned out Google was doing almost the same thing with its Screenwise app, and Apple’s ban-hammer fell again.
