See, this is what I'm talking about. If you're trying to protect activists from threats, protect them from threats. Making a political statement about commercial surveillance isn't doing that. A lot of these guides are LARPs.
How about this: if you feel strongly about commercial ad surveillance vs. susceptibility to drive-by RCE exploits loaded off web pages, look to see if the "infosec for activist" guides you're reading at least offer their readership the choice of risks. Does this one? (Rhetorical, obvs.)
