@projectgus Often when it comes to privacy, people speak of tradeoffs. As in, what's being gained and what's being lost. With Legacy IP (whether rotating or CGNAT), the proposition is a nebulous gain of non-correlated addresses. But the guaranteed loss is: no end-to-end connectivity, necessity of STUN/TURN, breakage of p2p, and difficulty/impossibility of hosting game servers.
#IPv6 avoids all those problems and is the modern protocol. Non-correlatability isn't worth giving those features up.
