I was reading this
https://stratisplatform.com/2017/03/02/stratis-breeze-wallet-redefines-financial-privacy-for-blockchains/ where Adam Fiscor is quoted saying
“Everyone who is not using Bitcoin Core has already had all their addresses linked together by third parties. This is not a theoretical “assume the worst case” strategy, this is reality. The third parties are either the central servers your wallet relies on or in case of SPV wallets all Blockchain surveillance companies.”
Why is this not a problem for Bitcoin Core?
To me 'all their addresses linked together by third parties' makes absolutely no sense.
Edit: I can only imagine he is talking about SPV wallets and their reduced security. We need to trust them about the legitimacy of the blockchain data it provides to the user. But still they don't 'link together all their addresses'
