When bitcoin first appeared I imagined a world of peer to peer payments with no central institutions. LN is most definately not that.
The graphic tries to show how funding a channel is like funding a 'hot wallet'. A more accurate description is that funding a channel is like depositing money with a bank.
I always said LN will be supported by big money. No doubt there will be an epic pump, because 'scalability is solved'. I don't like it but I can profit from it. The original dream of bitcoin doesn't exist though.
Wrong. LN is just a spec, how it is implemented will be up to the service. For example, it could go through a series of TOR nodes (slower), or could be implemented by the likes of expressvpn and such - or vendors will choose a solution for that, hopefully making a choice will be easy. There are tons of options, and if you don't like any of them, you can still stick to segwit
