There are still a handful of mass-produced performance-oriented road bikes out there with rim brakes:
Colnago V3R
Pinerello Prince FX Ultegra
Giant TCR Advanced 2
Wilier GTR Team
SRAM still sells Force 11sp mechanical with rim brakes too. (They also make 12sp AXS with rim brakes, but I guess part of the rant is about electronic shifting?)
