It is exasperating to read comments like this about Schneier in particular, who has been beating this drum for a long time, and whose anxieties about surveillance and the power it concentrates have been wholly decoupled from the politics of who wields it.
What has changed under Trump is that the power is now concentrated in tiny hands that seem particularly like it to abuse it, unconstrained by social norms or political checks. But Schneier wrote entire books about the dangers of surveillance culture back when we all thought Trump was a joke.
Before you say things like "why only now", take the two minutes it takes to discover whether this is in fact a new topic for the speaker, or if they have a history of addressing it.
