Yeah until you realize that e.g. docker compose doesn’t care about ufw rules and expose defined ports anyway (yes, through the firewall) and now you can argue that an inexperienced user doesn’t know this and thinks that the ufw will protect him and give him a false sense of security. You should always make sure to bind internal services to 127.0.0.1 only period. Anyway that doesn’t mean ufw is useless, but that it should only be used for filtering more than the default port allow rules because like this you have no security advantage (e.g. I use ufw on my Proxmox servers to block outgoing connection to the lan by default and then explicitly allow connection to server x if needed )
