I'm not debating the validity of the article as the author knows more than me on the subject. But one thing I will say is do they really? (ISP's know what you are accessing) Because when FireFox announced support for this technology there was a massive uproar from ISP's culminating with Firefox winning the 'Internet villain' of the year prize.
So exactly which part of the exchange can the ISP's see?
They cant see the DNS queries as they are encrypted and not using ISP DNS servers. Deep packet inspection will not get much back as the bits on the wire are encrypted.
That article seems muddled. Some are saying it's fake privacy whilst at the same time given an argument to the contrary.
At the end of the day I put my trust in
this. Essentially it tells me no one listening on the wire can see my DNS queries.
