I don't agree.

Looking at the design goals of 5G, the next generation networks will be 
engineered for massive device scale and very different traffic patterns. 
The small packets (backscatter or scanning) killing signaling (and battery 
life) in 3G is done a lot better in LTE, and most likely in 5G it'll be 
even less impacting.

For mobile operators there is a huge incentive to block incoming 
connections to mobile today (3G) but less so going forward. Handset 
manufacturers also have a huge role in this in hardering their hosts so 
that they can actually handle being exposed to the Internet (they already 
are by large I'd say) and ask the baseband vendors to not implement 
filtering there (I don't understand why someone would do that, the 
"computer part" of the device can't be that bad at handling incoming 
connections, right?). I can understand wanting to save battery for 
customers by the ISP filtering unsolicited packets in 3G, but not going 
forward.
