I would like to suggest that you focus the presentation on a particular audience.
infographic should be short and fun to read as far as I know. This is kind of boring to be honest.
IMO it's too detailed and looks like it's targeted for tech savvy or computer science student.
I agree that is overwhelming, and boring. I think the main problem is that is to technical with regards to following the connecting lines.
I don't see why CT/Confidental transaction is grouped with CoinJoin since both of them aren't dependent to each other
It is meant to be read as two types of confidential transactions: coinJoin and Stealth transactions.
The reason for including VPNs, TOR, and types of confidential transactions is to showcase the layers of abstraction used to create private transactions. For example using CoinJoin to open and close lightning channels over Tor etc. I think the infographic may be trying to bite off more than it should. I thought that including the sattlies could showcase how decentralized the network will become in the coming decades. Just imagine a country trying to censor packets that are being routed around their firewall by satellites performing onion routing.
