Overwhelmingly these guides seem to come from InfoSec or civil liberties focused individuals, groups, or NGOs, but bloody hell, the danger they face tends to pale in comparison to what radicals face, and the level of concern they have is likely far lower than it should be. Watching across the pond at this advice circulating, all I can think is that such liberal notions of rights are security are going to get activists killed or imprisoned for life.
(not that my advice is perfect. always get a second source. compare what we/i have written to these liberal guides, and diligently study where and how they diverge.)
