The reporter of the article should have informed it's readers that the person named in the article has a biased view on privacy because it is that persons job to make sure privacy rules and law are respected and followed. His view on law breakers is exactly the same view as some in there and that view is because there are other means to catch the bad guys there is no reason to stop E2E. That's a very bad view in my opinion.Interesting view from the UK's Information Commissioner:
End-to-end encryption protects children, says UK information watchdog
Information commissioner defends value of privacy protection in face of government-backed campaign
End-to-end encryption protects children, says UK information watchdog
Information commissioner defends role of privacy protections in face of government-backed campaignwww.theguardian.com
The NSPCC are quoted in the article and I feel their view is more balanced on the issue of protecting children and privacy matters.
