Why are people so disparaging about IHDs?

This may explain my confusion.Within a home there will be a Smart Metering System (SMS), typically comprising of Electricity and Gas meters, an In Home Display (IHD) and at least one WAN modem. Of course, not every home has a gas supply, and some solution approaches could result in the WAN function being physically delivered within the same box as the electricity metrology.
As I have no gas supply, my smart functionality is all in the same box.
Edit. On closer examination it does look like I have two boxes that appear to merge almost seamlessly.

Sometimes you can't tell the pedants from the ironocists. And don't get me started on the trolls and wind-up merchants!
And just as it was becoming clear, it now seems that the communications hub and the electric meter are actually two different things (boxes).

You say the IHD accesses the data in the smart meter via wifi
And I say
No it doesn't, HAN is not wifi.0 -

What do you think HAN stands for?
There is no physical connection, how do you think the data gets to the IHD?0 -
