I think this is undercutting the announcement. A baofeng is a specialized tool specifically for RX/TX 2m and 70cm analog audio radio waves. Of course it can listen to walkie talkies which are transmitting on 70cm.

I read your comment as someone posting about making toast with an iron and saying "Anyone can make toast. I can do it with my toaster. It's not that interesting"

All things that device can do is interesting because it is so many things, including this new ability.
