There are phones, that run GNU/Linux distros, that give you a working software firewall. Pointing at blobs doesn't make it not GNU/Linux on a phone with a firewall. At best it points to a place where a firewall could be undermined, but if that's your standard then (nearly?) everything fails, including actual literal firewall hardware appliances (I'd take Linux nftables on a blobbed network card over Cisco any day).
