This was an interesting interview.
Privacy is a concern. It would be good to see the product offered in some of the open source routers. How much information can be leaked with your commercial routers. There are so many layer where you privacy can be compromised. With VPN, I'm concerned is the leaking of DNS data. A lot of the US carrier mobile companies are hijacking DNS requests. Thus, meta data is being leaked. Keeping your privacy on the internet is a full time job.
