I kinda disagree.
I'm interested in reasons why Bitcoin is not implementing a feature designed for Bitcoin by Bitcoin developers and this feature is being used by a competitor.
The feature is immensely valuable and Bitcoins lack of privacy is insane. I can watch friends wallets and determine when they go to an exchange, JustDice or even blockchain.info (Blockchain is very tell tale because they always make the change address the address you send from.
Of course none of this is 100% certain, but it's worse privacy than a bank account.
The Bitcoin core developers seem to see the need for privacy and EdDSA/ring signatures:
Perhaps soon we'll see a high privacy sidechain based on this tech, but for now it's implemented completely in CryptoNote coins.
