No phone on earth runs the open source version of Android that you can download from git. They all run custom versions that include not only closed source personalizations to the system, but they also run lots of closed code as root (play services first and foremost). The reason why this doesn't happen with Android is much more mundane: most Android phones are not encrypted so the FBI doesn't need help to read all the customer data. They just need to open the phone and dump the flash.
