This would seem, to my recollection, to be more the sentiment that Tsing was rebutting, albeit at a time when the Web was still finding its footing as an "application" space, the friction of Berners-Lee's very intentionally stateless architecture only beginning to give way O'Reilly's era of interactivity. (The first Web 2.0 conference was the year prior to Tsing publishing.)
Which is to say, Kemper's observations are situated within an era of digital design that itself arose response to friction (statelessness) that had itself been introduced in to resolve a prior friction of client-server architectures ("We're waiting for our systems to update", says the telephone customer support person at the bank, as they wait for what amounts to a dumb terminal screen to refresh.)
Granted, Tsing was doing environmental ethnography (rain forests), not digital ethnography (such as web sites named after rain forests), but the urge to eliminate friction vs. the celebration of friction would perhaps be said to have a long history.
Swing of a pendulum, or sumfin'.
