[atlas] Non-public probes?

Hi Ernst,

> Just recently I realized that a probe can be labeled as “non-public”. Why is this allowed? Atlas is a community effort. Why are probe “owners” allowed to have benefits from using Atlas without sharing data?

Probes marked as as non-public have some of their details hidden, 
notably it is not easy to find their exact IP address. However, they are 
still participating in all available built-in measurements and are 
available for scheduling for user-defined measurements, and all data are 
available publicly for public measurements (but see the recent proposal 
regarding non-public *measurements* at 
https://labs.ripe.net/author/kistel/five-proposals-for-a-better-ripe-atlas/ 
.

The hosts of "non-public" probes are therefore contributing very nearly 
as much to the network as everybody else. :-)
