So, let me get this right: the only way you are allowed to critique the system is to make yourself irrelevant by becoming a techno-luddite, turning your back to society, disconnecting and disappear into the woods to live of the grid and self sustaining? All the critics must shut up because they don't have an alternative (although if they give an imperfect alternative you probably wouldn't deem it feasible). This is bullshit and self serving.

It's like saying you aren't allowed to hate petrol cars because you use a petrol car. The concept of technology being solely the domain of capitalist is ludicrous. The invention of technology is not bound to our economic system. This is a presumption that is not based on history nor empirical evidence.

So critique of the system is something that can be done even if you like technology.

I would think someone who identifies with hackers would understand this.
