When I were a lad, name-dropping Douglas Hofstadter's "Magic Cubology" (Metamathematical Themas) in this context was de rigeur.

Actually this is a rather 'thin' pop version of an idea proposed by Peter Carruthers. His 2011 book "Opacity of Mind" definitely is not a light read but makes a very compelling case indeed. If this is your jam, I highly recommend this book.

I run this site : https://ducis.net/ It is a hobby that got out of hand. The idea was/is to see what this data reveals. What can be learned just by observing 'traffic'. The answer is : a lot and I know various agencies and governments freaked out when they realized how visible some things are. Basically, with enough 'training' and domain-knowledge it's all pretty much out there : military transports, private military contractors, refugee flights, mercenaries, embargo busters, the spooks etc. Obviously there was a reaction. Over the years they've tried to tidy things up with some success by putting pressure on the tracker-sites (or simply attacking the small players' servers). Anyway, the point is : it is complex and fascinating. I'm not interested in shouting "SECRET flight..." for clicks but if someone wants to try and set up a new 'ADS-B Exchange' : basically free, responsible, open source etc and wants to take on board a couple of years of deep domain-knowledge and decades of coding skills, contact details are on the site. I know this is like a shameless (well) plug but...it's complicated ;)

So no one has heard of RFC6648 ? https://tools.ietf.org/html/rfc6648

I think that something must have gone awry with the interweb-thing when the physical location of a 'resource' becomes an issue.

I bet that the guy that lost the wallet, the stranger that found it and the guy that put the picture of said girlfriend up on the interwebs, are now having beers in that very same bar payed for by the girlfriend.

Byzantine red-tape, corruption, a legal framework that makes the Talmud look like a minor collection of one-liners, add to that a somewhat xenophobic business environment and an economy that's moribund and you've got the least favorable place to start a business : Greece. (I speak from experience. I'm sure Kafka was Greek.) The easiest, in my experience, is The Netherlands.
