Probably because of this: https://duckduckgo.com/?t=ffab&q=UPnP

Among the 4 first links, 3 explicitly tell me that UPnP is dangerous.

UPnP is significantly less dangerous than forwarding all UDP ports to a single device.

Came here to say this. UPnP is a security vulnerability, not a feature.

Worse than forwarding all ports?

Neither is an acceptable solution.

Although I will say that if you are forwarding all ports, at least it’s to a device you know about. Not some random IoT or PC software or whatever opening up ports without your knowledge.
