Re: So, the conclusion is ..
Personally, I thought the interview was clumsily handled and John Oliver did himself no favours with his playing to 'the Russians are gonna get me' cold war gags. Normally very fond of his shows, this one not so much.
To be honest, that's what I originally thought too, but I have changed my mind (took a fresh one from the freezer etc etc). I'm the first to agree the interview was far from perfect and I am frankly still stumped to find a real focus point in the whole duration, but it did one thing that nobody else has bothered with: it started to address the "so what?" factor for Joe Public.
The topic privacy has been made very, very complicated, not exactly helped by technical people slinging jargon at it as if that improves the quality of their warez. As with the finance industry, I am reaching the conclusion that that complexity is not by accident. People eventually go numb, even if the topic at hand has the potential to negatively affect their lives, and I have spoken with various journalists who have detected a sort of "Snowden fatigue", not helped by the fact that the average tabloid reader (of which there are many) has been trained to have the attention span of a mosquito on acid.
The mechanism was IMHO very crude (but that may be me being old fashioned) but what he did was strip out all the BS, all the stuff that plays peripherally but distracts, and make it real for people without going completely into "think of the children" pictures-of-your-teenage-daughter mode - also because it would otherwise lose its audience (it's still comedy, albeit with a more realistic edge). Sometimes, knowing too much doesn't help getting the message across.
The result was that, on reflection, the interview has more value than I originally picked up, because the current problem with privacy (as amply demonstrated by the interviewees, selective or not) is that the majority of people are not really aware of what is happening and what the consequences are, and even in a pretend democracy, the "majority of people" means the majority vote (it saves having to rig the voting system with all the risks inherent, but e-voting discussions are for another day).
Was this a good interview? No, it was only moderately entertaining, but for a first attempt at bringing something down to a level for mass consumption I do think it worked - now this approach needs refining (and maybe a bit less crude). Privacy matters, but the collective *we* (of which I deem myself part after enough coffee) need to find more tools to communicate exactly WHY. In that context, I liked the interview.
