Exchanges are businesses, so by definition they're "centralized." If you're concerned about KYC there are several exchanges that don't require it, but I don't trust any of them. You can try P2P like localbitcoins and similar sites. Or, post here on the forum in the
Currency Exchange board, you might find someone willing to trade with you. If you do post for an exchange here I suggest you use escrow.
I agreed with you. Centralized or decentralized exchanges, they are only different in ways they operate but they have a common thing, ownerships of exchanges is a kind of centralization and all sorts of exchanges have to follow laws of local governments.
Decentralized exchanges don't mean that they are now owned by anyone, any founders. They actually owned by one founders or group of cofounders.
