Re: A flaw in his argument
"addresses need to be assigned to physical locations, and even mobile phones need to talk to towers, metadata can be gathered, stored, and analysed, if deemed necessary. This is surveillance, and encryption will not help against it." --- TFM Reader.
Encryption can help against it, for instance, I can post the following AES256 encrypted text here:
Quite a few people are going to see that, but only the people who know the password are going to be able to read it. So the mechanics of using encryption to obscure metadata can be relatively simple: you can broadcast encrypted messages to a wide group of people including your receiver, but in a form that only they will understand (numbers stations seem to have been doing this for decades).
Of course, the legality of it is something else. In the UK, as I understand it, having this message in your browser cache, and being unable to produce the key when asked, could result in you receiving an effectively infinite prison sentence, served out in 2 year chunks. In the short term, I can spare you this ("password") but in the longer term that legislation needs to be removed. That gets us back to the real problem - how to get people engaged.
