這則從 Nuzzel 上看到的，國外討論得很凶：「Facebook pays teens to install VPN that spies on them」。
Facebook 付錢給使用者，要他們安裝 VPN (以及 Root CA，看起來是為了聽 HTTPS 內容)，然後從上面蒐集資料，這本身就不是什麼好聽的行為了，但更嚴重的問題在於包括了未成年人：
Since 2016, Facebook has been paying users ages 13 to 35 up to $20 per month plus referral fees to sell their privacy by installing the iOS or Android “Facebook Research” app. Facebook even asked users to screenshot their Amazon order history page. The program is administered through beta testing services Applause, BetaBound and uTest to cloak Facebook’s involvement, and is referred to in some documentation as “Project Atlas” — a fitting name for Facebook’s effort to map new trends and rivals around the globe.
這個計畫在 iOS 平台下架了，但 Android 平台看起來還是會繼續：
[Update 11:20pm PT: Facebook now tells TechCrunch it will shut down the iOS version of its Research app in the wake of our report. The rest of this article has been updated to reflect this development.]
Facebook’s Research program will continue to run on Android. We’re still awaiting comment from Apple on whether Facebook officially violated its policy and if it asked Facebook to stop the program. As was the case with Facebook removing Onavo Protect from the App Store last year, Facebook may have been privately told by Apple to voluntarily remove it.
