This week in privacy, NYT editorial board published an OpEd in defense of privacy. Jillian York at the EFF writes about the right to anonymity. Brian Armstrong shares his views on financial privacy and Zcash gets a mention. Twitter changes its data sharing terms and some people are not happy about that. That’s it for now. Have a great weekend y’all!
