All untrue.
Segwit will enchance bitcoins privacy.
because ALL transactions will be collected in (pre witness) state before it gets written to the blockchain.
so what happends is that when segwit is active only mixed transactions will be put in the blockchain , the transactions are total sums of multiple transactions done in (pre segwit networks) like the lightning and tumblebit network! when segwit is active,.....
So after segwit activation bitcoin will be VERY anonymous!
