What makes Sailfish OS unique over competitors like GrapheneOS and e/OS is that it’s not based on the Android Open Source Project, but Linux.
Not only are AOSP and its derivatives also based on Linux, they are actually free software unlike Sailfish OS which contains some amount of proprietary code (I know at least the Android compatibility layer - which I’m told isn’t simply the AOSP runtime (as Waydroid uses) but some proprietary thing).





It does seem like a bug. I actually have a UnifiedPush distributor but have never configured Fennec to use it (I didn’t even know it was an option) but now Fennec shows me this warning and there is no way to actually enable it in settings anymore.
