Could you be more specific? Zeynep Tufekci has actually been out in Hong Kong talking with and reporting on the protesters and their tactics, which your organization --- in her telling --- got comically wrong. Where is she mistaken?
There are many points which I have spoken about in multiple places. On the things she legitimately pointed out that I got wrong I put my hands up (like the flag things), admitted were incorrect and quickly changed.
A number of other things she said were partly/entirely incorrect, did not apply to us or could not be refuted in a public forum without admitting to previous experiences or potentially endangering people we work with in HK or elsewhere.
If you want more detail my email is in my bio and I am always happy to speak with people who are doing their best to help people at risk. Hence I am not being cynical, I actually am curious about whether you have used Umbrella? You talk as if you have so I am curious to know what we could do better...
