Moglen pointed out all the problems with Facebook (and Twitter) without showing the benefits.
He was asked for the problems. It's not his job to advertise social networking services.
One of the big figures of Software Freedom is asked about the drawbacks of social networking services and you start your argument with saying that he doesn't talk about the benefits. And then you compare the drawbacks to the ecological damage of washing machines (with the recent advances in efficiency, nobody is making as strong a point against them as you are trying to force). Nope, sorry, that's a straw man. And a very weak one at that.
I think if anything, having those three big issues out there (privacy violations, tracking by government, careless spreading of the two into the social graph), Mr. Moglen would be correct to say that the cost is already too great to be weighed against with any benefits.
I don't think I misrepresented Moglen's position in anyway. He only spoke about the negative aspects of social networking, but nothing about the conveniences. Argument by analogy isn't a strawman.
I agree that recent advances in washing machines have improved them, and that the environmental impact of them is far outweighed by the convenience.
Indeed, that is my point.
For me - and many others - the convenience and advantages of social networking outweighs the costs. I make that decision in full knowledge of those costs, and I think it is fair to point out that there are advantages as well as costs.
Person A: Sunny days are good.
Person B: If all days were sunny, we'd never have rain, and without rain, we'd have famine and death. Therefore, you are wrong.
Problem: B has misrepresented A's claim by falsely suggesting that A claimed that only sunny days are good, and then B refuted the misrepresented version of the claim, rather than refuting A's original assertion.
The benefits of social networks are self evident - they enable communication in an unprecedented way. His argument is that the drawbacks he is talking about are unnecessary and dangerous and that some of the technology may seem useful, but is actually just thinly disguised non-social behavior ("keeping up" with somebody may border on "stalking"). You have not addressed any of his arguments while complaining that he didn't address points that nobody was discussing to begin with.
So yes, one more, final, time - your argument is a straw man.
You could make the same point more civilly.
