Can someone explain to me, preferably in baby words, why so many providers
view information like https://as37100.net/?bgp as secret/proprietary?
I've interacted with numerous providers who require an NDA or pinky-swear
to get a list of their communities -- is this really just 1: security
through obscurity, 2: an artifact of the culture of not sharing, 3: an
attempt to seem cool by making you jump through hoops to prove your
worthiness, 4: some weird 'mah competitors won't be able to figure out my
secret sauce without knowing that 17 means Asia, or 5: something else?

Yes, some providers do publish these (usually on the website equivalent of
a locked filing cabinet stuck in a disused lavatory with a sign on the door
saying ‘Beware of the Leopard.”), and PeeringDB has definitely helped, but
I still don't understand many providers stance on this...

The computing scientist’s main challenge is not to get confused by the
complexities of his own making.
