Messaging app Signal down; company says experiencing technical difficulties

Brian Acton, founder of WhatsApp, who invested $50 million in Signal and turned it into a foundation, recently told CNBC-TV18 that data protection and privacy were at the core of Signal’s philosophy.

"When you have these relationships with companies where they may have access to your data, they can surprise you in ways that you really don't expect," he said and added, “Sometimes you are happy and you are delighted and sometimes it just feels downright creepy. Personally, I don't think that that's how I would like to operate my business. I would like to operate with more straightforward candour and transparency.”
