Really ?
Read the first paragraph of your post;
"What I’d like to see is some way to get better insight into the actual utilisation of TTN community gateways. This is often part of the discussion about the so-called fair-access-policy or fair-use-policy, described here: Fair Use Policy explained
Discussion can get very passionate about this topic, to the point that threads about it are closed / hidden from view. But are the assumptions from the policy actually verified?
Many might assume from that; if a Gateway utilisation shows to be very low you are questioning as to whether the fair access policy is valid.
Maybe I got it wrong ?
