> The point I was trying to make is that Google and Facebook have direct access to all the data of their customers, and already provide access to government agencies. Contrary to Apple they don't safely store some data of their costumers safely on the device, which this case is about.
Your point is wrong regarding Google and smartphones if the smartphone is encrypted
There's a huge distinction between Google (Android) and Apple (iOS) though: Apple affirms they don't have your keys, and this case bears that out (else the FBI would obtain the keys via subpoena to Apple rather than asking the court for a circumvention tool). Google is ambiguous about whether they have your Android keys; they claim they don't, however if you forget your device password it is possible to unlock your device via your Google account on a PC[1], and that alone is telling. If this were an Android device, the FBI would have already unlocked the phone with a simple subpoena.
Beyond that, Google definitely has the keys to your encrypted backups on their servers, so access to the phone might not even be necessary.
"The situation is different for Android. Google’s version of Android, which runs on most Android smartphones and tablets in the western world, only implemented encryption by default with the latest version Android 6.0 Marshmallow released in October 2015."
That version of Android is only on a handful of devices, not even a full percentage point of global market share. Even on Lollipop and older devices that do support encryption, it has to explicitly be turned on by the user. And once again, Google is not expressly clear that they don't have your encryption keys on Lollipop and lower; they only claim not to have them for Marshmallow devices. They definitely have the keys to your encrypted data on their servers no matter what, which can include complete backups of your device.
