This is still true. Since most Android phones and all iPhones cannot install freedom software, they don't have to explicitly put a DRM at the hardware level, because it is already there from Apple or most Android manufactures. Apple devices can only install software from a signed key. Most Android phones can only install Android from the device manufacture signed key (unless Google Pixel for example). However, Android allows installing apps from not just the Play Store on most devices, so either the Android OS would need an update, or the hardware would need an update.
