hmhmmm - not far away from the truth - yeah - but maybe a too simplified view
is a little bit like saying that the sea is a centralized channel that must be passed if you want to participate in world wide trading
centralized it might be if access could be restricted - but by design nobody can be locked out … so it’s as decentralized as it can be … decentralized but interconnected closely … a lot of different safe internets that can’t talk to each other wouldn’t be of too much use for humanity … but one large network that can’t exclude anybody but by design gives secure access to everyone - doesn’t necessarily make it a centralized thing imo …
