Can't speak for OP's link, but as a contrast No Trace Project's resources contain lots of advice from people who actually routinely face state repression, with in-depth analysis of specific cases. The scope is international (though focused on the North Atlantic region) rather than english- & u.s.-exclusive. There are plenty of references to Tor+Tails.
I see https://infosecforactivists.org/#acknowledgments and https://github.com/InfosecForActivistsTeam/infosec-activists... but I don't see their experience following their own advice.
The document by itself looks unpolished. Tor, for example, should be at least referenced once, even if they recommend against it.
