How far can such a device reach in a typical urban environment with the longer antenna?
The only thing that really helps extend the range is elevating the antenna, and repeaters allow you to do that even between two mobile stations.
So maybe the 1w is also a regulatory issue.

But in general, yeah, unless you do it regularly, living near sensitive facilities (airport, military base, hospital, factories, research labs etc) or deliberately transmitting at/near emergency frequencies (police, paramedic etc) at most you'll get yelled by a pissed off operator (at that point, stop, they could be already coordinating with someone else to triangulate you)
We need a compact short wave transceiver device actually.
And I know, I know, Baofengs are notorious for going over the allowed noise limits… but still…
Most people know that just about every Android phone has a restricted hardware design, not an expandable one.
So, "turn your phone into X" is bound to automatically evoke images of another device that plugs into the phone via common connectors like USB or the audio jack and an app on the phone to control that device. That's what the phrase means to most people in the context of Android.
"Turn your phone into a ham radio transceiver controller" is neither needed nor entirely accurate, because then people will assume it can control _any_ ham radio transceiver.
The two don't add up, and your apologetic analysis doesn't convince me otherwise. It's still clickbait. An Android cell phone has radio guts, and that headline is just gutless.
