I agree that by pointing out how technology can potentially make the problem worse, the essay can easily be interpreted as a call to throw out the baby with the bathwater.
Perhaps that was the intended message, but I'd like to think it was deliberately provocative to stimulate the right kind of thinking.
However,a technological solution can still help. For example, focusing on plausible deniability, traffic hiding, dead man switches and so on. Technology is just another approach and for some it might be easier to work with for some and easier to disseminate.
